Ok so this place is awesome if you want to sell your car to them. I was approached by Mohammed and Hazem over text for $21k on a car with 91k miles. The interaction with them even before walking in was super respectful and they were very patient because I couldn't sell right away. But even though they weren't there when I walked in, their colleague Danny helped me out with the deal and he was as great as Mohammed and Hazem. They do real inspections of the car. And when they come back, they show you pictures of the problem. And they tell you an offer. I asked if they can do more and they did budge a bit more but couldn't get close to the original $21k offer due to two issues I wasn't aware of (so that's very respectable). they also didn't significantly drop their offer NOR did they make it sound like you had a trashy car , just because of the two issues (one with the tire and leaking axel ). The process is easy. 45 min inspection. Paperwork took another 30 mins, negotiating can increase your time there. You sign all the documents to allow them to do the dmv paperwork. And don't worry if you have a lien on your car, they do the math and cut you the check based on what you owe and they handle it with your lender. They are very friendly and super nice. The facility is super clean and welcoming. They had the TVs set to the World Cup matches. read more

STG Auto Group of Montclair - The front of their entrance - Used Car Dealers Near Me - Montclair, California

I've had an oil change scheduled for about three months. I arrive and have been told it'll be a two hour wait. (what's the point of having an appointment?) I try to get the manager to prioritize my vehicle due to an appointment, she got frustrated and irritated with me. This is the service department. So if I were you skip the free oil change and pay at Jiffy Lube. Save yourself two hours read more

Just for an oil change, I waited over 3 hours with little to no communication unless I asked for an update. Every time I've made an appointment here, I'm never actually seen at my scheduled time. I'm a very understanding and patient customer, but when it's consistently hours past your appointment, it becomes frustrating. I'd say if you schedule any service here, don't plan anything else for the day because you'll likely be waiting a long time. It's better to come expecting a full-day wait. The staff is nice, and I do appreciate the service advisors, but I'm just being honest about the wait times. read more

STG Auto Group of Montclair - Just the business logo - Used Car Dealers Near Me - Montclair, California

It's really no surprise that at this time they have a 2.6 star rating. The car buying experience is great. It's after you leave that they are no longer accommodating. We were promised a bumper repair upon purchasing the vehicle. Vehicle was purchased in January and we have yet to be able to get a hold of anyone to schedule repairs. It is frustrating to be sent a text saying "what can we help you with" and when I respond, that is the end of it. When I call, I am on hold for no end. Even that our salesman hasn't followed up once to even see how we're liking the car is unfortunate. Makes me reconsider recommending it to others. Please listen to your reviews and make it right. read more

If you're looking into a dealership that is very pushy and does not respect your communication, then this is definitely a place for you. I was in the market to look for a new vehicle & I came across this dealership online. They did have a car that I was interested in, so I set up an appointment. On my way to my appointment, my car broke down from the freeway. Also, I was coming from close to 50 miles away. I informed the dealership about my situation and I had 2 different salesmen messaging me: Noah & Cesar. My car actually had broke down on the side of the freeway where steam was coming out of my car. I understand that Noah desperately wants to me a sale but he would not respect or understand my situation. He only wants to make sure he put money in his pocket. That being said, it's completely up to you if you want to work with them. I haven't even step foot into that dealership & I definitely know I will never do so after this experience. read more

They can improve by not lying. The price of the vehicle goes up as soon as you sit down. They added $10,000 onto the price. They wanted to charge extra for the wheels, tires, gps and more. I refused it all. When they finally agreed to not charge me for it. They said they use one bank to finance. I filled out an application and my credit alert texts when crazy. 8 credit inquiries in a few minutes. I walked out on them and they called for days. I had to block them. read more

I recently purchased a Porsche, and this was, without a doubt, the best car-buying experience I've ever had. From start to finish, the process was smooth, professional, and incredibly efficient. Christian and Rene, the manager, went above and beyond to make everything easy and enjoyable. Their positive energy, honesty, and knowledge immediately stood out. There was never any pressure--just genuine guidance, transparent communication, and exceptional customer service. They respected my time, answered every question, and made the entire experience seamless. It's rare to find a dealership team that truly cares about its customers, and Christian and Rene exceeded every expectation. They made buying my dream car an exciting and memorable experience. I couldn't be happier with my new Porsche, and I highly recommend working with Christian and Rene if you're in the market for a vehicle. I'll absolutely be back for my next purchase and will be referring my friends, family, and clients to them. Thank you both for an outstanding experience! read more

WORST DEALERSHIP I HAVE EVER WORKED WITH!!! They gave me a guaranteed offer on my trade in and they wouldn't make a deal for the new car over the phone they were insistent that if I come in they will do what they have to do to earn my business so I drove 2 hours to get there just for them to pull out on the deal last minute. They had me there for 3 hours negotiating cause they wouldn't honor the offer and they kept manipulating the contract acting like they were going to give me better deal when really they were just moving money around from one fee to the next like I wouldn't notice so in reality it was never a better deal. DON'T WASTE YOUR TIME!! read more

I recently called about getting an oil change (today on June 9th 2026) and the next available date for an oil change, nothing more, is on July 15th, 2026. Thats well over a month without being seen. This place is absolute TRASH. The lady I spoke to over the phone was eating the whole time, literally, who does that?? Customer service is a dumpster fire.... I was better off paying thousands more at an actual dealer. At least the buying experience and maintenance would've been better and faster. DO NOT BUY FROM STG AUTO!!! you will pay dearly..... ​ read more

After 1 week of ownership I come to find I had BROKEN MOTOR MOUNTS, FAILED WATER PUMP, AND BENT CONTROL ARMS. SHADY SALES TACTICS, NO PRE INSPECTION OF AUCTION PURCHASED VEHICLES. AVOID RAMY AND STG AUTO. I don't see how this "dealer" has any reviews higher than 1 star. I purchase a 2018 ford explorer with very good mileage back in 2023. I really wish I would have read the real reviews, but I did not. This dealers tactic to bring you in to see the car is a below market value price tag online: once you get to the dealer the price is marked up anywhere from 3-5k in dealer ad ons. Absolutely unnecessary. When I went, they said the car was on the lot. Well, it wasn't! It was at a different location and I waited 3 hours for it to supposedly arrive but actually never did. Then they asked if I wanted to go in and talk numbers while it supposedly was on its way. After talking numbers and learning that the price was not as advertised, I almost took my business elsewhere after not willing to pay for fake ads ons that weren't even on the vehicle yet. Well let's get to the next important part : Dealer agreed to drop price so I moved forward, upon arrival on the vehicle which was the next day inspected and found a lot of hidden small damage to the car. They said they would fix it which they never did, the also said the vehicle would arrive detailed because of my wait and it was actually very dirty inside and out. It felt like a big mind game going on with this salesmen and dealer. Because I got the car to my price and I liked the vehicle I decided to purchase it and go forward on my own financing which they pushed against. AFTER 1 WEEK WITH THE CAR I COME TO FINE OUT IT HAS BROKEN MOTOR MOUNTS, PARTIALLY TORN SERPENTINE BELT, BENT CONTROL ARM, and a DAMM FAILED WATER PUMP. After further investigation I learned that this car was purchased from an auction and then sold. So what comes to mind is that STG MONTCLAIR never inspected the car before selling and did any necessary repairs that were needed. Thankfully I had purchased a warranty from an actual ford dealer separately which covered my costs. What did STG do for me? Nothing. They basically told me that was too bad and the car was sold as is. Guys, on top of that as I was originally getting an uber to this location my uber driver told me he bought a car from stg and it was a lemon that had nothing but problems. The signs were there before I even went to this dealer and my experience matches countless others. Avoid this place at all costs. RAMY YOURE A YOU KNOW WHAT FOR TAKING ADVANTAGE OF PEOPLE. . read more

1 Star - Stay away from STG Auto Group Bought an Acura RDX here on 3/13/26 and it was hands down the worst car-buying experience I've ever had. They lied about add-ons being mandatory, claiming we needed them to get a lower interest rate. That's not true. I even found paperwork during signing that clearly said the add-ons were optional. When I questioned it, the salesperson literally admitted he doesn't like working there because of how they do business. They also told me dealers can't mark up interest rates in California anymore, which is false. Later, someone from their team accidentally confirmed the bank approved me at a LOWER rate than what I was given. We put $5,000 down ($2,700 cash), and they refused to give a receipt for the cash. The car had a brake issue the SAME DAY we drove it home (braking on its own + warning light). It's now been in their shop for almost 3 weeks with: no updates conflicting stories constant runaround I was hung up on by their finance manager and even dealt with someone who gave me info and later turned out they have me a name of someone that did not even work there. This place has zero integrity. Just pressure tactics, lies, and terrible service after the sale. Save yourself the headache--go somewhere else. These guys are scammers: Sales: Georgio (should be how you spell it) Sales Manager: Anthony (bald with tattoos on his neck) Financial Manager: Chris A. (Very childish when speaking to you, over talks you and hangs up on you mid conversation) Fake guy: Tony Suarez read more

STG Auto Group of Montclair - Used Car Dealers Near Me - Montclair, California

I had a disappointing experience with this dealership. Shortly after purchasing my vehicle, I noticed that the engine did not appear to be in good condition, and the car began leaking oil on the very first day I brought it home. These issues raised serious concerns about the vehicle's safety and whether it had been thoroughly inspected before being sold. When I contacted the dealership and returned to discuss the problems, I was told that repairs would require additional charges. I attempted to follow up multiple times through calls and messages, but many of my concerns went unanswered. I was also very concerned by my interactions with the manager, Fernando. In my experience, I was told that my vehicle would not be repaired unless I removed my negative review. I felt pressured to take down the review in order to receive assistance with the problems I reported. As a customer, I believe vehicle concerns should be addressed based on the condition of the vehicle rather than whether a review is posted online. I am sharing my experience so that other potential buyers can make an informed decision. I hope the dealership improves its customer service, communication, and vehicle inspection process for future customers. read more

Completely dishonest and Renee the manager is a FLAKE AND A TERRIBLE MANAGER!!!!! They tell you everything you want and as soon as they make the sale it's crickets. They lie about the listed price, try too add things on, and then never follow through with what they tell you at the sale. I had to have the car shipped to me, ($2k delivery) the driver showed up after being called and given a heads up a day before and then the morning of and the driver showed up and no one could find the keys! I had to reschedule the driver and got the completed run around from these clowns. Now the car shows up and there's no temp tag now they're saying I couldnt register it on your state?!? The dealer is required to issue you a temp plate! AVOID THE HEADACHE AND AVOID STG read more

This place has such crappy service. We all know that car dealerships purposefully leave you waiting for hours so that you can get tired and not have the energy to negotiate a price on a vehicle. But this place seriously sucks. We came to purchase a car and we noticed that there was a sound that was made when shifting, they said they would fix it for us. So we took it to a mechanic after to ensure everything was OK and guess what? It had still $800-$1000 in repairs that still needed to be done. We tried to ask them to do it and they said yes but only if you guys pay 50%. So we asked them to knock off the $1000 from the price we paid and that we just leave and have it redone somewhere else. They countered and said they would only give us a couple hundred back. Would not recommend this place. To anybody. Not even if you live across the street lol My thing is, respect people's time. Just tell us straight up from the get-go what it is. "Yes, there are some issues with the car that need to be repaired, but we're only willing to meet you at $$$." Point made, we can all move on with our lives... Such a waste of time. read more

I had my Porsche Boxster S for sale on auto trader for 52k. Jackson who works in the office offered me 48k and we agreed on 49,750. Lie number 1. Because we agreed on that price I took my car to sell it to them driving 30 minutes each way to get there. They kept me there 2 hours and came back to offer me 47,500. So right off the bat I was LIED to again. Then they offered me 48k and I left. I hate liars. So two hours later I get a call from the manager Klaus, saying the reason they changed the offer was because the transmission had a leak. Funny there's NEVER been a puddle under my car. Then they said the two back tires were different, big deal, they're expensive speed rated tires, a chip on the windshield (another LIE), and "many costly repairs" All total garbage to get the offer low. Jackson wouldn't even come out to talk to me. I was told that the repairs will cost too much to do so they're just going to sell it AS IS. What a crock of shite. This is classic bait and switch. I brought my car back the next day and sold it to them because I didn't want a hefty repair on the transmission which is very suspect. They low ball and lie. NO ONE came out to talk to me, not even Klaus. I'd call that UNPROFESSIONAL... BAD customer relations. I brought an important document of MINE for them to COPY not KEEP, instead Sammy kept it. I need that back by the way. Will I get it? Probably NOT. Fits in with the rest of my experience here. I would say, BUYER BEWARE. I read other reviews before going and they're very bad, (good thing I wasn't buying anything). I can see why. The best customer service there was their free soda. They have nice cars and a LOT of vultures, sales people, on the lot. When I got home I had a text asking me to remove my bad reviews. So I changed them with brevity in mind. I am waiting for the check to clear the bank. I don't trust LIARS. I would NEVER recommend this store to anyone because I was lied to. Look at the other reviews to see how they treat buyers and decide for yourself. I feel sorry for the person who buys the Porsche because they said they're not going to fix anything they had issues with. AS IS BUYER BEWARE. Shame on you STG for your shady business practices. I would NEVER buy a car from you. This is based on my experience and their bad reviews. I've owned a lot of cars in my long life and STG ranks up in my top 3 WORST auto dealers. My suggestions: better customer service and less time on your computer, dress professionally, don't walk around VAPING, stay with your customer during the transaction and don't lie to customers. I'll never return. Now they're selling my car as is with all the issues. BEWARE OF THESE CROOKS. IT DOESN'T HAVE A SECOND KEY because I lost it and look at the damage on the bumper and wheel they didn't fix. Mismatched tires still there? Ya. read more

Do not bother trying to sell here, they will waste your time. Had my wife come in at 11:30 and told her it would take a hour, ended up being much longer. When she got there they made her wait for their lunch break to end, and then had her run to different parts of the building to get help and still had to wait another 30+ minutes on top of that. She took time off of work to come in just to lowball us on very minor cosmetic that would be expected with a car at 98k miles when we had said the major issue over the phone which was a small chip in the windshield and still had a agreed upon price before agreeing to come out to avoid this exact situation. She asked for the inspection report and told her they sent it to me and sent her on her way, all I received was an updated offer with the new lower price. Unprofessional and rude to my 9month pregnant wife. (UPDATE: so after blowing my phone up trying to get a deal done they finally offer a additional $200 for disrespecting my wife/wasting her time and so we agree upon the price and they ask for my wife's number to call to confirm. They call her and they sit there on the phone with her ranting getting upset with her for 5-10minutes just to say they won't go over 11k again. Thanks for wasting our time even further) read more

They'll say just about anything to get you through the door. They offered significantly more for my car than seemed realistic, only for me to arrive for my appointment and wait over 40 minutes. If you're curious, ask the people sitting in the lobby about their experience. Several mentioned what felt like bait-and-switch tactics. Once I realized what was happening, I took my car and left. Since then, they've been calling and texting me nonstop, even increasing the already unrealistic offer and insisting it would only be honored if I came back that same night. When I declined, they told me I was being unreasonable. The constant pressure felt very pushy and unprofessional. Even the manager called me personally. He asked how often I'd been contacted, then immediately tried to negotiate and asked what the lowest price I'd take for my car was. It was clear the high initial offer was just meant to get me in the door. Overall, the experience felt sketchy, overly aggressive, and not somewhere I'd recommend doing business. read more

This is a text response from someone I was dealing with at this company after I asked for them to be professional: Sure, so i tried to be friendly as much as I can but you want it professional. Alright, professinaly the numbers aren't helping to offer the same I'm doing since December. So YOU need to be professional and start the process that you requested. It won't need anything from you except uploading some paperwork that will be on your phone. So you can still make it abroad even. So that's not an excuse. Professionally, my offer has expired. Thank you! read more

Save yourself the time and go somewhere else. My girlfriend and I came in to look at a car that was listed online at a specific price. They sat us in a room and made us wait while the salesperson did the classic "let me talk to my manager" routine. The manager came in, made small talk to build rapport, then told the salesperson to "give us a good deal." After more waiting, the salesperson came back with a breakdown that was just the same online listed price with a bunch of add-ons tacked on, no discount at all despite the whole performance. When we pointed out that this wasn't actually a deal and said we still wanted to look at other options before deciding, the salesperson literally got up, took the paper off the table, and walked away from us. We asked him to give us the sheet back and he kept walking and basically hid from us. We just left. Classic high-pressure sales tactics from start to finish. If you're not ready to overpay on the spot, they don't want to deal with you. Plenty of other dealerships out there that will treat you with basic respect. read more

The reason for the one star is the bait and switch tactics by this dealership. I understand dealerships need to make money on cars they buy. STG made me a very generous offer of 15,000 over the phone. I even verified whether my vehicle would be subject to reappraisal after inspection. I was told no, that it was "guaranteed," which led me to believe 15k was what I would get (lie #1). I made the one hour drive to Montclair and waited another hour for my vehicle to be inspected. I was then offered 14,700 due to a leaking shock, which I was unaware of, and brakes that needed to be replaced (lie #2). I know this was not accurate because I had the tires replaced less than 1,000 miles ago and was told I had 30 to 40 percent brake life remaining. At that point, I asked for my keys so I could leave. The inspector said he would speak to the manager. He returned 15 minutes later and said 14,700 was the best offer. I took my keys and left. Before I even reached the freeway, the manager called me. He explained why I should take 14,700 and said it was a fantastic offer, which I agreed it was. He talked over me and was very pushy until I told him to stop and let me speak. I explained that my issue was with the principle of the deal. He then went into a speech about how he is honest (lie #3) and trying to get me the best deal possible. We both explained our positions. I told him I understood he needed to make money and said, "after you fix the car, you're probably going to list it for 16 to 17k," based on similar cars on the lot. He responded that if he sold it for 17k he would make a huge commission, but claimed he was listing it for 15,500 and that there would be no profit after repairs. He continued to push, and I continued to decline the 14,700 offer based on principle. He eventually said he was not the one who texted me the offer, claiming he is just the inventory guy and does not deal with sales (lie #4). I pointed out that if he earns commission on a sale, then he clearly does deal with sales. I told him the statement was not honest and that it was fine we did not make a deal. Overall, I would not recommend this dealership as they wasted my time and fuel. They will find issues with your vehicle, and a "guaranteed" offer over text can change. just something to beware of when selling with STG. read more

I got an offer on the phone and we both agreed after back-and-forth conversation. I then decided to drive a couple hours for the offer and after 5 hours, inspection is done and the manager said I need four new tires. I showed the manager the paperwork from the dealer service that all four tires are good, but then he ignored it and decided to stick with the outcome. I ask him can you please show me how this is check. The car inspector came out and check with his tire checker. We check 2 tires. When he check it it was marginally on yellow and green. But when I push it, it was on green. tire thread checker need to be pressed firmly and since he was testing it on the side of the tire instead of the top, it's not accurate. I also ask him if he have another tire checker to verify just to double check his tire checker is not defective, but he never came back. Since I drove 2 hours and have been there for 5 hours, I had no choice but to take the offer which he significantly reduces the amount the was originally offer to cover for all 4 tires. If I ever have to do it again to sell my car, I would not sell it to them and just sell to Carvana. My car only has 6000 miles 2025 Almost new and tires need to be replace? From my experience, I would definitely not go through this hassle and selling my car there based on what I've experienced. Have your car check and tires check by tire place and bring your paperwork with you because they will try to find ways to reduce the offer. read more

I would not recommend relying on offers from STG Auto Group in Southern California, even when the offer is provided in writing. We drove approximately two hours after receiving a written/text offer of $24,000 for my Tesla Model 3. The vehicle is a one-owner, garage-kept car with low mileage, a clean vehicle history report, and no accidents or damage reported. It also has a professionally installed satin 3M wrap, which was clearly visible and part of the vehicle's condition before we came in. Before we made the drive, Klaus called me and confirmed that the $24,000 offer took into consideration the scratches and dings that had already been disclosed in the listing/photos. Based on that written offer and conversation, we made the trip. After we arrived and they completed their inspection, they suddenly said the wrap was an issue and lowered the offer to $21,000 -- a $3,000 reduction from the amount that got us to drive there. Klaus then stopped responding to my texts and calls while we were at the dealership. This felt like a lowball tactic after getting us in the door. It wasted hours of our time and was extremely frustrating. I would caution other sellers to be very careful before driving any distance based on an offer from this dealership, even if the offer is in writing. read more

The customer service while you're there is excellent BUT once you drive off the lot it's a whole different story. Got my car on Sunday night Monday morning it wouldn't start the battery was dead, both of my key fobs were dead. Reached out to the salesman and he told me that these things happen! Service department had to have the car towed to them so they could replace the battery. Not even a week later I find out that the vehicle has a recall for the electric battery that could and may catch fire! Clearly they do not inspect the vehicles, they do not service them and they are selling them and putting peoples lives at risk for whatever commission is that they are making off of the buyers. I wouldn't be surprised if they have a lawsuit coming or already have some read more

We had a great experience selling our car to STG Group. Danny was fantastic throughout the entire process--professional, responsive, and easy to work with. When the initial offer came back lower than we were hoping for, Danny went to bat for us and was able to get a price we were happy with. The whole process was fast, easy, and stress-free. We really appreciated his effort and excellent customer service. Highly recommend Danny and STG Group if you're looking to sell your vehicle! read more

Awful place to buy a car. Not even a month after purchasing a car 2 service lights came on. I'm currently sitting in their service department going on 4 1/5 hours. Reception desk very lazy. I literally had to roam around the office to try to find a employee named April and then after I came back around to the service department, the girl was like oh it's in the back they're still running a diagnostic. I may be a women, but I know it does not take hours to run a diagnostic test. I had an appointment and watched people come and go all day and sat as patiently as I could and just waited. Don't waste your time or money here. So looking forward to whatever BS they are going to try and tell me. read more

Very sketchy place. Had us sitting in waiting room for 3 hours after taking our car keys and not providing the check. I believe it was due to the manager not wanting the check they were issuing to be cashed before 4pm. All they had to do was ask (it was a large check). Instead they kept stalling. Lots of odd people. Never going back. read more

I have bought 4 cars from STG Auto since 2024, and they have honestly been a staple dealership for my family. Unfortunately, the customer service and overall quality control have severely declined over time. This complaint is mainly about the condition vehicles are presented in at sale and the lack of follow-through afterward. When I purchased my Tesla, it was at night, and I will take accountability for not specifically requesting a test drive -- but one was also never offered. The car was delivered with scratched rims, empty brown coffee cups left inside, and despite keeping me waiting an additional 45 minutes for "detailing," the vehicle still felt rushed and poorly prepared. The car also creaks while driving, which I chose to overlook. What really pushed me to write this review is the license plate situation. STG taped paper plates onto the vehicle but failed to include the proper Tesla front license plate bracket required to legally mount the plates. I was told by the salesperson to simply contact the service department and they would "handle it." I scheduled a service appointment, drove out there, and then was told they did not even have the parts available and would need to order them. My question is: why was the appointment confirmed if nobody reviewed what the appointment was actually for? Customers should not be sent away because the dealership failed to prepare for its own scheduled service appointments. Now, over a month later, I am still being told the part has not even been ordered yet because they are "waiting on accounts payable." Meanwhile, California law requires proper display of license plates, and I am the one driving around stressed about expired temporary tags and improper plate display because the dealership failed to complete something that should have been handled before delivery. At minimum, consumers expect a vehicle sold by a dealership to be road-ready and legally compliant. I have continued giving STG chances because of my family's long history here, but this experience has honestly been disappointing and frustrating. read more

Just like everyone else. Scam. It's been a while since a dealership caught me this off guard. Called about car. Said it was there. Confirmed for my son, drove in. Someone called and texted while in route to Montclair. We arrived & no car. No apologies. We left. A wasted trip. Truly unprofessional. read more

If I could give zero stars I would. Please read and listen to the other bad reviews this place will scam you. I purchased a car with them I told them I wanted to finance with schools first they said okay we can do that. I sign all the papers and they come back and mention that they don't have the title it can take a month or two to get it so schools first might not finance the loan. They said I can pay and get the title expedited. I said no I'll wait I want to finance with schools first (I have an audio recording of this BTW). They come back (and lie) and say their manager is going to pay out of pocket and get it expedited cool right. Two weeks pass I get two letters one from Global Credit Union and one from Schools First both of them congratulating me on my auto loan. I had two auto loans. How you may ask? The dealership flat out LIED TO MY FACE. They looked me dead in the eyes and lied with no remorse. That's who you're buying a car from if you come here. Now I'm left with the mess of trying to untangle my TWO LOANS. The most upsetting lie about all of this. I called global credit union asking if they received the title of the car from the dealership and when... they received it the day I signed the papers for the car. THAT MEANS THEY TRIED TO STEAL MONEY FROM ME "PAYING" TO EXPEDITE A TITLE THEY ALREADY POSSESSED. If you don't want to be lied to and robbed go to literally any other dealership. Attached is a transcript of the audio recording where DANIEL was told clearly that I wanted to finance with schools first NO OTHER CREDIT UNION. Either he doesn't understand what words mean or he's just a slimy piece of shit. read more

STG Auto Group of Montclair - Used Car Dealers Near Me - Montclair, California

I had a very disappointing experience with STG Auto Group due to misleading communication. I was contacted regarding a 2020 Subaru Outback Touring that was advertised online. Before agreeing to come in, I clearly explained multiple times in writing that I live over an hour away, do not have a second vehicle, and would need to take a rideshare. I specifically asked not to come in unless the vehicle was available and my financing had been reviewed. STG Auto Group confirmed in writing that: * The vehicle was available * My credit had been reviewed * I was pre-approved * I should come in that day I also received an appointment confirmation from a sales manager. Relying on these assurances, I traveled with my 7-year-old child, spending about $180 on Lyft rides. After arriving and waiting for nearly an hour, I was told the vehicle had already been sold. I was then shown other, more expensive vehicles. I was never notified beforehand that the car was at risk of being sold, even while I was en route and in active communication. I understand first-come, first-served sales. The issue is confirming availability and approval in writing, knowing a customer will incur significant costs to get there, and then failing to update them. I have documentation of the text messages and appointment confirmations. Based on my experience, I would recommend getting everything in writing and confirming availability immediately before traveling, especially if you're coming from far away. read more

This place won't stop calling you to invite you to sell your car with them. I came all the way from Los Angeles to get an offer that was $4000 slower than what was agreed on the phone. Please just save yourself wasting time with this business and do not trust Mason read more

They didn't fulfill their promise. They promised to provide us with the missing carpet for the pickup truck in one week before the deal was made. I didn't receive it after a week and went to follow up. They promised another week. Today, it's another 2 weeks , I am here and waiting for the salesman . I will let you guys know if there is any response. read more

STG Auto Group of Montclair - Used Car Dealers Near Me - Montclair, California

Came in to check out a used BMW M4 Competition at STG and the experience was underwhelming. No one greeted me when I walked in, and staff at the front seemed more focused on their phones than customers. I was also told I couldn't test drive the car without first completing a credit application, which felt unnecessary just for viewing the vehicle. During my visit, I inspected the car mostly on my own while the salesperson remained disengaged. The M4 itself also had more cosmetic wear than expected for its year and mileage, including exterior and interior flaws. Overall, the visit didn't reflect the level of professionalism or quality I would expect when shopping for a performance vehicle, so I decided to leave. read more

STG Auto Group of Montclair - Car I bought from STG - Used Car Dealers Near Me - Montclair, California

Bought a car from them. Had some service issues that were to be fixed. Services was supposed to call. Never did. So I called service they put me on hold every time I called and never answered the call. Continued to put the call on hold without so much as a word. Sat on hold 20 minutes each time I called. Then tried to contact the salesman and manager and no one answers their page, phone calls, texts or messages asking to be contacted. This has gone on for 2 days as of now. There is only a 30 day warranty. 1 week down. Will be notifying the Better Business Bureau read more

Beware of STG Auto Group Montclair - Dishonest and Unprofessional I purchased a 2022 Nissan from STG Montclair in August 2025. From day one, the car has been leaking fluid under the engine every single day. When I bought the car, there were already small issues (scratches, noise, not properly cleaned). The sales promised me: "Close the deal first, bring it back anytime, and we'll fix all the small problems right away." Once the deal was closed, they stopped responding. The manager never returned calls. They only replied when I left negative reviews, and even threatened me to remove the reviews before helping. Customer service asked me to pay extra, even though these were problems they promised to fix when I bought the car. It's been over a month and the issue is still not resolved. I spent hours calling, waiting on hold for over 1 hour with no answer. If you value honesty and after-sale service, do NOT trust STG Montclair. They only chase you before closing the deal. After you pay, they ignore you. I'm now filing complaints with BBB and California DMV for their dishonest business practices. read more

"S" stands for scammers. They will lie and say whatever they can to get you in the door then pull the bait and switch. Whether you're selling or buying they're one of the worst I've dealt with. read more

I don't give out 1 star reviews often, but when I do, they are deserved. Our original salesperson was friendly and forthcoming, but every person after that was rude, unfriendly, and dismissive with every negotiation concern or question we raised. Went to check out a truck listed for 37,000 online, they tried to say it was 56,000 instead, trying to charge us for all of the aftermarket items the previous seller put on it. Remy, the manager, tried to talk down to us and was the most unpleasant individual I have ever dealt with, never wanted to make a deal. Rude, incompetent salespeople. Don't buy a car from these crooks, they will rob you blind and fiddle while your family's life burns. Will never buy a car from these people, and advise you not to either!! read more
