I recently bought a car from AM and worked directly with Carlos Lopez. Carlos was outstanding--knowledgeable, responsive, and incredibly helpful throughout the entire process. The pricing was reasonable, and there was absolutely no pressure--just transparency and candor from start to finish. I had a very solid experience with AM and truly enjoyed working with Carlos. read more

CONSUMERS BEWARE! PUBLIC SAFETY AND SECURITY ANNOUNCEMENT: We weren't coerced or bribed with things of value to write a positive business review of Auto Merchants Inc. This is an authentic business review of our interactions with the owner/Sid S. and his employee/Octavio C. over the previous 900 days, as it relates to the owner's grossly past due insufficient funds check. NOT REWARDING DISHONORABLE CONDUCT: It's more important than ever for a consumer to do their due diligence in sufficiently investigating the individual or business they are considering investing their hard earned money with, and only reward individuals and businesses that operate ethically, legally and constitutionally at all times. This objective, to the best of our knowledge and recollection of facts and/or opinion based business review will assist in that mission, as it relates to Auto Merchants, Inc., for the best predictor of future behavior is past behavior! INTRODUCTION: An insufficient funds check is a serious civil and criminal offense that is actionable under Texas Business and Commerce Code 3.302 (holder in due course) and Texas Penal Code - Chapter 31 -Offenses Against Property (THEFT). This legal and constitutional protected business review is designed to kindly compel Auto Merchants, Inc. to comply with Texas law, and the fiduciary responsibility of their company established by the Secretary of State, and immediately resolve the balance of their grossly past due insufficient funds check on file at Lee's Check Cashing without further subterfuge and/or obfuscation and/or delay. 1. Check date: 5-2-23, check # 5980, amount: 3000.00. Receiver of funds: Octavio C. Total balance due NOW: 1500.00 + 900.00 (reoccurring administrative resolution fees) = 2400.00. FACTS OF CASE AND CONDITIONS OF THE LAW: On 5-2-23, Auto Merchants, Inc. issued a check to an employee/Octavio C. for duties/services performed. The employee cashed the check at Lee's Check Cashing, and the check was returned to the check cashing establishment due to insufficient funds, because the check issuer intentionally stopped payment on the check within hours of issuing the check. Subsequently, over the next 150 plus days, the owner of the check cashing establishment contacted Auto Merchants Inc. and/or the receiver of funds in order to compel them to comply with the aforementioned Texas check laws and resolve the grossly past due insufficient funds check. Due to the refusal and/or failure of Auto Merchants, Inc. to comply with Texas check laws, their unpaid check was delegated to the authority of the Loss Prevention Department to facilitate immediate resolution. The owner alleged (without proof) his account was 'hacked," as the justification why he stopped payment on his check. He alleged the employee was given a 3000.00 dollar replacement check and snapped; "you better check our records!" If true, he did so without using basic business common sense, in first verifying the legal holder in due course of his returned check, and if the employee deposited the initial check into his bank account or cashed the check at a check cashing establishment. The employee was interviewed to verify the owner's claim. The employee alleged he was confused and thought the 3000.00 dollars was his, since the check was written in his name. The investigator helped him realize how preposterous his claim was received, so he confessed to intentionally embezzling the 3000.00 dollars in funds that were legally required to resolve the insufficient funds at our check cashing establishment. The owner was informed multiple times in writing and text, if he paid the employee to resolve his insufficient funds check, and he refused and/or failed to resolve the check with the legal holder in due course, his check is legally unpaid, and he is legally required to immediately resolve his check at our check cashing establishment, and he may file embezzlement charges against his employee for the alleged theft of his 3000.00 dollars if he refused and/or failed to return the funds he allegedly stole from him. The owner defiantly and irresponsibly refused and/or failed to comply with Texas check laws, and instead offered to pay 300.00 dollars every two weeks until paid in full, lending to the reasonable speculation the real reason he stopped payment on his check is not because his account was "hacked," but because of poor money management and/or lack of sales revenue due to poor, substandard business practices. At the point the owner's unpaid check was approximately 250 days past due Texas law, he finally made one measly 300.00 dollar payment on 1-24-24, and subsequently four more 300.00 dollar payments on 2-8-24, 3-6-24, 4-3-24, 5-8-24 and abruptly stopped without the consent of the victim, leaving a balance of 1500.00 dollars for over 575 days; in the process ignoring two certified letters, and over 100 text and phone calls to compel him to resolve the balance. read more

Auto Merchants - Proof of insufficient funds check. - Used Car Dealers Near Me - Plano, Texas

Dishonest and deceptive. Read the previous reviews. I was very hopeful when John was not giving the me the hard sell on a used vehicle. He explained that there was a perfect and clean title and Carfax for the Auto. I was interested in. Can you even imagine that he told me that when the car not only had a lemon law title issue, it also was a manufacturer buyback! But he continued to tell me there was nothing wrong with the car or title. Talk about untrustworthy. If you look in the reviews you'll find at least one person who bought one of these cars lemon and buyback and was never told about these major issues and even received financing without disclosing these issues. So please, Buyer beware! It's so sad that deception is such a big part of this industry. Makes it hard for anybody to be honest when you have to Compete with people like this who will do and say anything for Greed and profit. read more

Under no circumstance should anyone purchase a vehicle from here. They sold me a lemon without ever mentioning the word or that it had a branded title. It was phrased that "the vehicle was returned to the manufacturer but it's had no problems since"... Not to mention they omitted that information to the bank I financed with who told me they absolutely do not finance lemons, and that the dealer is absolutely responsible for purchasing the car back from me. I am now in a horrible spot with this vehicle because it breaks down every other week and the trade value is half what a clean title would be. Maybe I'm naive but I truly feel scammed by them. read more

This is my second purchase with Auto Merchants. Unfortunately, the "good" vehicle I thought I purchased now has a seized engine. (2021 Hyundai Palisade - bought Dec 16, 2025) Shortly after driving off the lot I began noticing something leaking in my driveway. The oil leak was there from the beginning, and it progressively got worse. You can still see the stains on my driveway until this day. Any basic inspection before putting this vehicle on the lot for sale should have caught this oil leak. Either they knew about it and sold me the car anyway or they failed to properly inspect the vehicle before selling it. Either way that is unacceptable. I contacted the dealership and brought the car back Jan 5, 2026. I left it overnight and they said the leak and some other things that I noticed upon purchase was fixed. Weeks later the car started sputtering and I discovered there was NO OIL in the car. I called the manager and he was no help. He insisted the leak was fixed but clearly it was not because the car had no oil. He then told me the vehicle had about a week left on the warranty and to contact Hyundai. When I contacted Hyundai they confirmed the warranty had already expired when I purchased the car. I added oil thinking perhaps Auto Merchants had not added enough during the service visit. I depend on this vehicle for work and my family. Hyundai would not cover it since there was no warranty. However, the dealership did not even remedy what they failed to fix correctly and just brushed me off to Hyundai. Fast forward to April 20, 2026, the car ran out of oil a third time and the engine seized completely. There is no low oil warning indicator on this vehicle (unless that just never worked either). I have had this car for about four months and am now being told I need a $10,000 engine replacement for an oil leak that came with the car from day one. Either they knew and sold it anyway or their inspection process completely failed me as a customer. This is not just bad business. This is negligence. I hope Auto Merchants makes this right. I have referred several people to Auto Merchants and this was my second vehicle purchase with them. My loyalty to this dealership makes this situation even more disappointing. I am beyond frustrated with how this has been handled and I hope they do the right thing. I also called on April 21st 2026 requesting to speak with the owner, Sid Sharbaf, and was told by a representative named Ray that someone would call me back within a few minutes. To this day no one has called back. read more

Total waste of an hour. Check in person was kind but salesman was disorganized and painfully slow. When I told him I needed to run some errands this afternoon so if we could speed it up I would appreciate it, his exact response was "well I don't rush young man" I'm 33 so that felt very odd/unprofessional. Maybe they play the used car nonsense of trying to ware you out with time but I left. read more

The salesman who sold us our Mazda wasn't 'helpful' -- he was running a full-blown magic show. He parked the car in the exact lighting needed to hide the swirl marks in the paint. Not a coincidence. That was intentional misdirection, and I fell for it. But the real insult was the story he fed us about the manufacturer buyback. He told us it was 'just something California does' -- like people get bored and turn cars in for fun. What a joke. It's a lemon title, and he knew it. He straight-up lied by omission and acted proud of it. We didn't learn the truth until multiple dealerships refused to even look at the car because of that title. Meanwhile, he stood there smiling like he was doing us a favor, when all he was doing was pushing a problem he didn't want on his own lot. Looking back, I'm sure he was outside doing cartwheels the moment we drove off. He got rid of a car he couldn't unload, pocketed the sale, and figured we'd never figure it out. Well, here we are. We figured it out. And I'm not staying silent so he can pull the same stunt on the next customer who trusts him. This salesman didn't 'help' us. He played us. And once the act was over, we were left holding a car other dealers won't even touch. Buyers deserve honesty -- not bait-and-switch theater. read more

I purchased a 2024 Mazda MX-5 Miata RF from Auto Merchants Inc. in September 2025. The dealership provided a CARFAX report showing no accidents. On their own dealer disclosure form, they wrote in "PRIOR UNIBODY/FRAME DAMAGE REPAIRED" and then wrote "N/A," next to it indicating no such damage existed. Since it was marked on their own disclosure it appears they were aware of the damage. After bringing the vehicle home, I discovered clear evidence of front-end collision repairs, including paint overspray, missing bolts, disconnected washer fluid lines, and makeshift fender repairs. Upon further investigation, I found that this same vehicle (verified by VIN) had been sold at Insurance Auto Auctions just weeks earlier with visible collision damage. It appears the dealership purchased the vehicle from this salvage auction, repaired it, and resold it to me without disclosing its auction history or prior damage--despite having a specific disclosure line on their own form where they marked "N/A." When confronted with this evidence, the dealership took the vehicle back but did not acknowledge any wrongdoing. The same car has since been relisted on their lot for more than my purchase price and is still being advertised as having no accident history. I'm sharing this to help other buyers avoid the same experience. I've since learned that not all body shops and insurance companies report to CARFAX or similar services so a clean report does not guarantee a clean history. Recommendations for buyers: * Always get an independent pre-purchase inspection * Run both CARFAX and AutoCheck history reports * Search auction databases (IAA, Copart, etc.) for your VIN * Carefully review all disclosure forms line by line * Ask directly whether the vehicle was ever purchased from an auction or repaired Buyer beware!!!! read more

I located a vehicle on Cars.com and called to make arrangements to see it. When I arrived, I didn't realize I had been there a couple of days prior to test drive a different vehicle. When I checked in, I was introduced to a new salesperson, Travis. Travis is friendly, helpful, and extremely knowledgeable. After test driving the car, Travis walked me through the Carfax report item by item explaining what everything meant. Travis did an outstanding job explaining the titling for manufacturer buyback vehicles which helped me understand why the vehicle was returned to the manufacturer and the repair that was needed. Travis was extremely patient and open to all questions I had. The next day when I returned to test drive a different car, it was ready and waiting for me. In the end, I didn't purchase a vehicle. I will definitely return and highly recommend Travis for the exceptional customer service he provided me! read more

This business never fails to impress me, they actually take care of their customers!! I bought a Ford Mach e mustang from Carlos who was very honest and catered to my situation not just trying to get a check. the car drove perfectly, the only problem I had with it was the tire sensors were off and not reading correctly, so I took it back after a week. It turns out the last owner didn't put the best quality rims on the car. Not only did they fix the tire sensor problem but they gave me brand new all black rims that were way better!! And I didn't have to pay anything! So please yall go her to buy your next car and ask for Carlos! He will hook you up! read more

They basically took my money and said the hell with you! I was going to refer people that was willing to buy cars from their show room floor. Don't ever get your customers twisted. My sales person was Ray F. I bought my car, and he straight ghosted me. Below is the last message I sent. Very disappointed in this so called "TRUSTED FAMILY OWNED BUSINESS" Hello Ray, I am very satisfied with the car. Everything we talked about as far as getting the car cleaned, the rear tow cover and the touch-up paint was not as told. The steering wheel, gear shift assembly, center console it appears to be an incident. They either spilt coffee, shake or could be vomit. They claimed to have taken it upstairs to clean it and didn't while I was there on yesterday. I'm having the car detailed now, and they are having to steam clean all the gunk off. They completely left me hanging. I'm not happy with the delivery. read more

My name is Eva and I previously left a negative review do to some issues I was having getting some promised repairs done on my 2009 Jaguar that I purchased from Auto Merchants. They have since made the needed repairs and were very curteous. I appreciate their willingness to work with me on this matter in a very professional manner. I would now recommend this dealership and Ray Fuentes to work with. Thank you again for following through with promises made. read more

It has been a few years since I bought a car there but after having horrible experience at competitor next door, I want to leave a good review for Auto Merchants. We purchased at least 3 cars over the years from AutoMerchants. All 3 cars I ended up driving for many years. On 2 of them I put over 100k miles and got great value. AutoMerchants do buy sone cars that have been in accidents before but that is disclosed. They are minor accidents that the car has been fixed. On one car when I had an issue weeks after I bought it, and went back thinking they would tell me it wasn't covered as no warranty, Sid took care of it. They took it to dealer and had it fixed, no issue. Another time I was looking for a particular car that I could not find. I told Sid what I wanted what color I wanted and he said he would see if he could find one at auction. Weeks later he called me and told me that he got one, but there was no pressure for me to buy it. I went, and he got me exactly what I was looking for and at great price. Gave me a good price as his overhead cost was low as it did not sit in inventory. I bought that VW and kept that car for years. Like I said it's been a while since I bought from AutoMerchants, but after buying from Auto Of Dallas next-door (and horrible experience) I would go back and buy from AutoMerchants. Honest, no hidden fees, good customer experience. read more

I saw the car online and choose option if available. I received text/email from Omar Alajami. We setup the test drive and Omar wasn't available at my time. He had Cristian take care of the test drive. He put a tag on it and let me take it for the test. After that we set down and went over the CarFax. Omar followed up and we discussed my concerns and the price. We settled on the price and then I was given the Purchase Order. This all happened with an email and many text. I was not able to accept the PO and advised I wasn't buying. Omar took this and after a short time called me. We made a deal and I was at ease. I had two more concerns and Omar got them resolved and we setup delivery. He wasn't able to make my time and Cristian took care of the paperwork. Simple and easy except for the name of my town. He had paperwork printed and highlighted. Thank you Omar for going above the normal process of taking care of a customer, me. I had no knowledge that my request were out of scope. And you went over and beyond helping me out with this deal. I learned a lot and grateful that you MADE it happen. read more

I bought my current car here 6 years ago and couldn't be happier. It was an amazing deal on a very low milage BMW with a lot of factory warranty remaining. I have since referred several friends who have had equally positive buying experiences. Travis is a great salesperson - low pressure, very engaged, and will make the process seemless. They have excellent finance in-house and I have since refinanced with the credit union they fit me with, even lowering my interest rate to an incredible 3 percent (that was 2 years ago). Everyone at Auto Merchants is very friendly. The owner and his protege son are on the floor and equally willing to help you have an exceptional experience. They will remember you when you come back and thank you for your business. I'm close to pulling the trigger on my next car from them, but it's hard to decide with the huge inventory of low milage, high-end cars. Go see Travis! read more

From luxury to economy to off road or even speed So many great options and deals highly recommend definitely will be back again

I was looking for a sedan with 30,000 to 50,000 miles. I found several at prices cheaper than CARMAX and Rental company resale sites. I drove several alone. There was no pressure from salesman. They had full Carfax reports. Mine did not explain why the driver door paint did not match the rest of the car. I purchased one and am very satisfied with it after 2 months. Only issue is that they added a $900 fee in the sales contract at the end. You can negotiate the price of their cars so be ready for this. read more

Called in today for a car I found on Autotrader and the guy picked up and told me to come on down to test drive. Drove 35 minutes and paid five dollars in toll just to get there when I reached there they made me fill out a form and then told me the car is in the shop and I could not view it horrible service would never step foot in that dealership again. read more

My experience was terrible. Ray Fuentes acted like he cared and was an honest salesperson. Unfortunately for me I was sold a vehicle that had not passed inspection. I was told the entire brake system had been replaced and had a year warranty. All lies I had to replace the full brake system and 1 of my tires had a screw in it, and 2 tires were down to the wire. 30 days after my purchase. The warranty on my brakes expired the same month they sold me the vehicle. I reached out multiple times asking for help was told it was happening. I asked for the simplest thing as well transferring my customer plates to my new car. Was told several times it was happening to only receive different plates. I never heard back from him or the dealership with any resolution. I have had to report them to the BBB. read more

Super livid with customer service at this place. They're great and listen up until your money is accepted

I saw two cars on Kelley blue book listed at NO ACCIDENTS from these people. Then I pulled the FREE autocheck report that is attached to every listing in the BLUE below the car in Kelley blue book. Guess what? Both were branded as LEMONS and one had a wreck attached. Who would resell cars branded as LEMONS? No thanks! I reported this to Kelley Blue book but they were very hands off, and did not do anything.. Just said that autocheck and these companies can falsely report at times, that mechanics may have put in the wrong information. But for two different cars and both branded as Lemons? And then they asked me if I had reached out to the dealer.. Another NO THANKS! Anyway, please check your car VIN before preceding with any car with a reputable VIN checking company. I use 4 now just to make sure, as some do say differing things as one I was checking out said NO ACCIDENTS on several of the reports but carfax listed a wreck.. BUYERS, beware!! read more

I was interested in the car in the photo below. I reached out to Auto Merchants via text on their website. I got a confirmation text that I was now chatting with Auto Merchants. No one ever replied. Since they don't give you access to the CarFax online, I paid the $39.99 to run the report myself. Sure enough, this vehicle was bought back from the manufacture under CA Lemon Law & then sold at auction; now here it sits. No mention of this on the website for this car. Not interested. read more

Bought a vehicle and noticed several small issue the day after when driving longer distance than test drive. I took it back and these guys said not my problem. Octavio, a salesman, appeared to listen when I said something needs to be done about these issues. Just for him to take my car into their shop and do nothing. No work was done and no one called me to update me on when I could pick it up. I am very sorry I ever have these incompetent, rude people my hard earned money. read more

Customer service was horrible sat there for an hour and only spoke to the guy 2 times and didn't even bring us to a desk had us in an open area speaking numbers infront of other customers. read more

My advice when going here DRIVE DRIVE AND DRIVE the vehicle you choose like really drive it. I expect to have some problems with used vehicles however to incur a maintenance bill within 2 weeks of purchasing a car is horrible. I have spent nearly $1000 just doing preventive maintenance on this car not to mention I brought it back to the dealership 2 times only to be lied to and the car still isn't right. Horrible buying experience and horrible vehicle. I will not return. PROCEED WITH CAUTION!!!! read more

Terrible!!!! I called on a Wednesday morning to explain that my wife and I were ready to buy a vehicle and wanted to drive off the lot by Saturday. I spoke with Travis and explained what we were looking for. He texted me one vehicle that didn't meet our criteria and never called me after. I texted him two days later to get a reply that he was headed back to the office and again never heard from him. With sales people like that Auto Merchants won't succeed. I will NEVER BUY A VEHICLE THERE!!!! read more

Just purchased my 5th vehicle from Auto Merchants, Sid and his son are awesome! Conrad was beyond exceptional! I have never experienced any problems, I am long time customer since 2009, I only purchase Auto Merchant vehicles.

I wouldn't purchase any vehicles from Auto Merchants. They are known for selling "bad title" vehicles. Horrible customer service and no willingness to make things right with you and make sure you pay close attention to the Carfax details the salesmen will try to a quick one. Not worth the effort or your hard-earned money spent with this company. Stay away people they are a bunch of crooks and thieves in my experience. read more

STAY AWAY FROM A MAN NAMED JOSE! because of my experience with him i will not be coming back to this place or referring it to anybody. every step of this process has been horrible. he continuously gave me wrong information causing me to waste time and money. he never had an answer for any questions or he's straight up confused. he has helped with nothing and just slowed everything down more and more. Overall a really bad experience and will not be back read more

Great experience, everything was smooth Travis and Ray were very helpful with our purchase. They also addressed every issue we found with the cars cosmetics and rectified the problem immediately. read more

If I could leave no stars I would. So I recently had my car refinanced and paid off my loan with this place and my new loan place had me call my older dealership to request for my GAP insurance check refund and I don't know much about cars and refinancing stuff so this place has poor communication they didn't tell me the right channels to go through to request for the refund back. It's been 6 weeks and I keep getting told they'll get back to me and they never did. I kept having to call and text to see if any progress was done and they kept telling me "let me check and call you back" this place has very poor communication. Finally today I learned through google that I had to request the check for my refund through my lender or dealership but the dealership was no help so i called my old lender. and before you guys say anything when i say dealership its he finance department of that dealership. FYI if you refinance your car be sure you're requesting for your GAP insurance refund through your old lender. Also make sure you check everything on the vehicle you buy. Because the vehicle I bought from them has problems. When it rains my trunk gets wet inside and my trunk is damaged and I have to slam it really hard to get it to close. I live far so I couldn't just bring the car back and it's my only car for my family. Overall I do love the vehicle just check everything before you commit. please work on your communication skills. read more

The salesman is very unprofessional I'm guessing because I'm young, made the mistake of letting them run my credit

They make the buying process very easy... but after that, you're on your own. I bought a used car from them April 30th (Saturday) By Monday morning (May 2nd) I noticed a few things wrong with it & called Hector (my sales associate) letting him know what was going on & if I could bring it back in to be maintenance... & two weeks later I'm still getting the run around. Do not recommend buying from this dealership. read more

I had 3 cars in mind, based on review of their website inventory. None of the 3s' Carmax link would work. Went to their store (very nice btw and a great, friendly, salesman) and looked at Carmax's there, 1) Accident, structural damage, 2) Accident, structural damage, 3) Lemon buy back. Just my experience, ymmv read more

I would NOT do business with these people! 3 days of pure unprofessionalism! I see the high reviews, but they must be old. My wife saw a listing with no pictures. The salesman Ara said he would send pics when it got off the truck. Never happened. We asked if we could come look at it, and made an appointment. We drove 1.5 hours. It took 25 minutes to "find" and pull the car up. We had given them 3 hours to get ready. Ara handed us the keys, asked for a driver's license and went back inside. No walk around, no focus on features, and no ride along. I felt like this would be a great place for people to steal a car due to the lack of customer service, and no attention to details. They quite literally didn't care if we were even there! We sent paperwork to financing, and were told they would call us the next day. No one ever called. When we called to set up an appointment with another salesperson (Raymond), he didn't even bother to show up.!! When I complained to a manager, Tommy, he didn't even apologize or do anything to make it right! When I complained we didn't even get offered a bottle of water, he said "Do you need a bottle of water"? No! The point is you should've asked. After waiting another 20 minutes (remember, I had an appointment)... they finally bring up the car. (Every other dealership in America would've had it washed and waiting). Then Ara comes and confronts my wife about asking for a new sales person.... and it wasn't his fault no one called us back! Keep going. These guys are worthless.

I worked with Josh to buy my car. Not only was he super easy to work with, but he was very personable and made me feel like it was my choice and I had no pressure to choose. He was flexible with my time and my decisions when looking at different cars. The process was smooth purchasing my car. Auto Merchants handles your new registration and license plates. I simply was able to drive my car off the lot and worry about nothing! I highly recommend Auto Merchants and working with Josh! read more
