    Dog hair and sand

    Shortly after purchasing my vehicle, I discovered significant dog hair and a strong dog urine odor inside the vehicle. This was especially concerning because my children have allergies to dogs and dog hair. I contacted Leo, the salesman, regarding the issue and requested reimbursement for the expenses I incurred addressing the problem. Unfortunately, his follow-up has been unreasonably slow and inadequate, despite my attempts to get this resolved. A dealership should stand behind the vehicles it sells and respond promptly when legitimate concerns are brought to its attention. I would strongly recommend thoroughly inspecting any vehicle before purchasing from this dealership.

    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.

    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.

    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

    The dealer charged me $1999 for a special coating on the car. The car was filthy. And that much tar on it. Impossible

    Be Aware!! I have to admit that the service I received yesterday at the Montclair location was the worst experience I've ever had at for a car purchase. Let me start that I text my interest of a vehicle that I wanted to see if it was still in stock. I received a quick response from Zack that it was. I told him I live far away so needed to know what I could expect to get as a trade in for my car. I sent photos and a VIN number. After over an hour I had to text again and I finally got response. I felt the number was fair. Gave him my credit score got a number and made an appointment for 330 the same day. What's so disappointing and started that experience was I drove all the way to Montclair arrived before 3:30 and was told that I would meet with Manuel Gonzalez. I thought that was odd since I had been working with Zach.. And later found out that he was In Egypt and was pretending to be a sales person to make appointments for the salesman. That's a major concern because Manuel didn't have any idea about what we had talked about. The worst part was that Zack Never ordered my car And it was way down in Garden Grove. So even though I had an appointment at 3:30 and told them they never brought the car to the Dealership!!! So I had to wait an hour and a half in a room by myself With absolutely no contact from the sales person or anyone else. I really Nothing that was going on. After waiting all that time, I finally got up And looked for my sales person. In which he said, I'm going to tell you The wrong car!!! I thought it was a joke. Knowing my situation. No one double checked.! They assured me it wouldn't be too long at 5:30 in traffic, And I then proceeded to wait another hour and a half in a room by myself With no clue what was going on, no Offer of water Or anything. I finally got a hold of the sales manager. Told him how disappointing and upsetting it was that I had an appointment and no one even bothered to bring the car To have the wrong car! We made another negotiation and I proceeded to wait again. Finally, the car And I said I would buy it and they said they would put And wash it and have it ready for me After I have the paper signed. After another hour and a half paperwork still was not ready. But Manuel assured me that the car was clean and gassed and ready to go. At 10:30 at night I was finally done. It took another hour and a half to get the paperwork signed Lo and behold I get a message that they're just now filling the car with gas and they'll bring it to me. Well, the car was filthy, had not been washed All over the side of the car was leaking gasoline!!! I got home at midnight with an appointment at 3:30 in the afternoon. I don't even want the car anymore. It completely ruined my experience And honestly, I felt like crying And they charged me $1999 for a special coating on the car. Will with all the tar and dirt on the car my detailer ( at home) said it had never been put on!

    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.

    Bye buddy

I purchased a 2022 Gray Mustang GT with 27k miles in July of 2026. When I arrived with pre-approved financing from my credit union, Westin started pressuring me to finance through their preferred lender instead before I even had a chance to look the car over. He told me I wouldn't be able to drive the car home that day if I went with my own financing because of DMV hoops. Understandable, as I am aware this is a tactic dealers use to push a sale. However, it made me feel an elevated level of pressure. I was in love with the car and willing to refinance after the purchase, but I will deduct half a star for this. I will deduct another half for this: I brought a friend who is a professional mechanic with Toyota to check the car out. Before the test drive, he alerted me to a leaking rear differential and low motor oil levels. During the drive, we noticed the rear-view camera wasn't working and a tire pressure monitor warning was lit. When asked about these issues, Shane told us the camera had an active recall and that the car had just been serviced (including a rebuilt transmission) with Puente Hills Ford, but they didn't have the parts to fix the camera and there was nothing to worry about with regards to the rear differential and low motor oil. My friend knows what he knows, and I found it odd that a vehicle would have low, dirty motor oil right after a major dealership service. The test drive itself sold me. A 5.0 Mustang has long been my dream car, and the after-market Borla exhaust (never mentioned online or during calls) was a sound I could never get tired of. My friend strongly advised me to take the car to a dealer to check the issues while it was still under warranty. Because it was, I went ahead with the purchase. The financing with their lender was quick and easy, done in about 45 minutes. Shane even threw in 300 bucks in cash to get the tire pressure monitors replaced (which I discovered later at Ford would cost about $700). I used his cash towards the down payment. There was an active recall for the rear view camera, which settled me on that issue, and overall the experience at Kutsch was smooth. I understand they are trying to sell cars, but I would appreciate more transparency. If you are not lucky enough to have a pro mechanic with you, or purchase a car that is out of warranty, you might get fleeced. This is true for any used car dealership. After purchasing the car I took it to my local Ford dealer, Ford of Montebello, for a diagnostic check. When the tech opened the hood he right away told me the car smelled like it was burning oil, explaining the low levels. The car spent 2 weeks at the dealer. The rear differential was indeed leaking fluid and had to be serviced, the engine had a bad front crankshaft seal that was leaking oil, and the transmission was actually fine and working like new. The recalls were taken care of, and I decided to ignore the tire pressure monitor warning since it is nothing major. All of this work would have cost about 7K if the car was out of warranty. I didn't pay a dime, but I did lose the car for 2 weeks. I also refinanced their 8.1% rate, no extended warranty or GAP, for my 5.3% rate w/GAP and extended warranty, and lowered my overall interest by about 4k. At the end of it all, I am really happy with my purchase and the overall ease with the process. There were no hidden fees or markups, which I did expect because of the Borla exhaust, but nope, none of that. The price advertised was the price I payed. No negative feelings towards Kutsch, Shane, or Westin, and I thank them both for their business, but you have to be careful. These dudes are overall friendly, and they do have a great selection of performance and luxury vehicles on their lot if you want something with lots of horsepower. I am enjoying the car, getting about a million smiles per gallon!

    BUYERS BEWARE - MULTIPLE PROBLEMS, SAFETY CONCERNS AND NOW SILVERROCK DOESN'T WANT TO COVER THE…read moreREPAIRS I wish I had paid closer attention to the reviews for this DriveTime location before purchasing my vehicle. After going through my own experience and then reading reviews from other customers, I am extremely concerned by how similar some of their reported experiences are to mine. I purchased a 2018 Nissan Sentra from DriveTime in Montclair on August 11, 2026. Shortly after purchasing it, I began reporting multiple problems, including CVT/drivability and acceleration concerns, A/C problems, a malfunctioning horn, speaker/radio problems, and Bluetooth issues. I followed DriveTime/SilverRock's repair process and took the vehicle to AAMCO in Rancho Cucamonga. AAMCO told me there was nothing wrong with the transmission and performed work on the A/C, but several problems remained unresolved. I then took the vehicle to a Nissan dealership, and Nissan has advised me that multiple problems still need to be corrected. Nissan identified a computer/software update associated with the CVT system that AAMCO had not identified. Nissan also advised me that the A/C compressor AAMCO installed was a used unit and identified a differential fluid leak. I also subsequently discovered that the vehicle had an open manufacturer safety recall before I purchased it, and I understand DriveTime was aware of the open recall before the sale. Now, after all of this, SilverRock is stating that it does not want to cover the remaining repairs. What makes my experience even more troubling is reading other reviews for this same Montclair location. One reviewer reported purchasing a vehicle and experiencing problems the same day. Another described mechanical problems within 30 days, repeated repairs and eventually an engine replacement. Another reviewer described discovering brake, motor-mount, oil-leak and other problems shortly after purchasing a vehicle and then having SilverRock deny some repairs as wear and tear. Those are other customers' allegations and experiences, not mine, but after what I have personally experienced, I wish I had read these reviews before buying my vehicle. In my case, I reported my problems, followed the warranty process, presented the vehicle for repairs while it was still within the warranty mileage, and gave DriveTime and SilverRock an opportunity to correct the vehicle. The problems still have not been completely resolved. This isn't a situation where I bought a used car and months or years later something broke. I began dealing with problems shortly after the purchase and have been trying to get them properly addressed ever since. At this point, I do not want another repair attempt. I want DriveTime to take the vehicle back. I have formally demanded that DriveTime buy back the vehicle, return my $1,800 down payment, reimburse the monthly payments I have made to the extent recoverable, and resolve the remaining financing obligation as part of taking the vehicle back. I have given DriveTime until Friday, September 25, 2026 to provide an acceptable written buyback resolution. If they refuse to resolve the matter, I intend to file a lawsuit and present my documentation to the court. I have kept records of my communications, repair attempts, warranty issues, payments, Nissan's findings, recall information and the problems I have experienced with this vehicle. My advice to anyone considering buying from this DriveTime location: read the reviews first. Have the vehicle independently inspected before purchasing it. Check the VIN for open recalls yourself. Do not assume that every problem discovered shortly after purchase will necessarily be covered by SilverRock. Get everything in writing. I hope DriveTime resolves this before litigation becomes necessary. If DriveTime takes the vehicle back and resolves this appropriately, I will update this review with the outcome.
