Recently I spoke to Rachel at Sewell over the phone regarding a car. Did she know everything about the car? No, she did not. But she tirelessly found the answers and immediately got back to us time and time again. So thorough, so responsive and so professional. She gave us the comfort level to fly in and buy a car. I have ALS, so travel is very difficult for me. Again, the comfort level to fly in and buy a car. Who does that? I had such a fantastic experience with Sewell.

I want to start by saying the salesperson was excellent—professional, responsive, and genuinely helpful throughout the buying process. Unfortunately, that was the only positive part of my experience. Sewell GMC of Dallas claims to perform a multi-point inspection on used vehicles, but based on my experience, that inspection is either not being done or not being done thoroughly. Upon delivery, the vehicle had multiple chips in the windshield that were never disclosed. These were only addressed after I specifically pointed them out. Additionally, the vehicle did not have a fresh oil change, which is something most buyers reasonably expect—... Read More

I want to start by saying the salesperson was excellent—professional, responsive, and genuinely helpful throughout the buying process. Unfortunately, that was the only positive part of my experience. Sewell GMC of Dallas claims to perform a multi-point inspection on used vehicles, but based on my experience, that inspection is either not being done or not being done thoroughly. Upon delivery, the vehicle had multiple chips in the windshield that were never disclosed. These were only addressed after I specifically pointed them out. Additionally, the vehicle did not have a fresh oil change, which is something most buyers reasonably expect—especially from a dealership with Sewell’s reputation. Even worse, the oil level was so low it wasn’t registering on the dipstick at all. This is basic maintenance and should have been caught immediately during any legitimate inspection process. For a dealership that markets itself as premium, the used vehicle intake and inspection process is subpar and disappointing. Transparency and basic mechanical checks should not be optional, especially when customers are trusting your inspection claims. I expected far better from Sewell. While the salesperson did their job well, the overall experience with the vehicle preparation seriously missed the mark.

Devosky Hall is hands down the best salesman I’ve ever worked with. Respectful, polite, and genuinely listened—it truly felt like he was on my side, not just chasing a sale. I was an out-of-state buyer looking for my wife’s Christmas present and dealt with several frustrating dealerships before this. In total contrast, Devosky and his management team made everything seamless and stress-free. The process went so smoothly I even double-checked with finance because it felt almost too easy. Highly recommend this dealership—ask for Devosky Hall. We’re proud owners of a pre-owned 2023 Tahoe Z71.

Multiple visits to resolve issues and some still not resolved. They don’t communicate or respond to concerns. Sam (service writer) is not responsive. Not even close to what Sewell stands for. VERY DISSATISFIED!

My salesperson was wonderful. I felt like I mattered and he listened to what I wanted in a new car. He was very knowledgeable of the options available and went the extra mile to look for a comparable vehicle. Thank you Steve!

If you purchase from this dealership, follow-up on the payment! Purchased 2 weeks ago, payment still not received by previous lender! They "dropped the ball" per the Sales Manager - no excuse! Only to discover, they sent it to the wrong payoff address so now a further delay. I have bought vehicles from Sewell Cadillac in the past and have NEVER had this issue or ANY issue previously with the Cadillac side. The GMC side has left a very bad taste in my mouth for purchasing from them again.

***CALL FAVOUR FOR YOUR NEXT ANYTHING!!!*** My career has been motorcycle sales, early on, my mentor had us read Carl Sewell’s book “Customer’s For Life” in “book club”. That book had always stuck with me as a guide on how to approach a sale, even if THAT SPECIFIC book wasn’t directly about about sales, more how to treat a customer in general.

***CALL FAVOUR FOR YOUR NEXT ANYTHING!!!*** My career has been motorcycle sales, early on, my mentor had us read Carl Sewell’s book “Customer’s For Life” in “book club”. That book had always stuck with me as a guide on how to approach a sale, even if THAT SPECIFIC book wasn’t directly about about sales, more how to treat a customer in general. Under promise, over deliver. When I saw my new truck at a Sewell dealer I was low-key excited, as a hustler to go meet some hustlers, and see if they lived up to what was pushed, HEAVILY, in the book. Hands down I was beyond impressed. I showed up looking like some kind of biker trash gremlin 2 days in a row, and Favour treated me like a human. I wasn’t there looking at the most expensive vehicle, far from it. But I was treated with the same respect I’d assume someone would receive from someone buying a vehicle 20x the cost It was a rad, and fair experience, and I genuinely am grateful to have been able to learn a little bit more from these guys, but more importantly Favour nailed exactly what I’d learned from Mr. Sewell’s book in the first place. Favour, and the rest of the team at Sewell 100000% earned a customer for life.

By far the best dealership / service department I've ever had the pleasure to deal with. I brought my 2021 GMC Sierra in on a Tuesday (no appointment) with a blown engine and had it back the same week with a new motor. Not only was this service done in a very timely manner, my service consultant (Jasmine Garcia) was very professional and called me multiple times to keep me informed during the process. Sewell gained a customer for life I can tell you that.

Easiest, most relaxed experience I’ve ever had purchasing a car. Blake was super helpful, intelligent, and was able to get us in and out quickly. Would recommend Blake and Sewell to any and everyone!

Dealing with Mike Cuellar was the worst experience ever. Sweet talker he is, he did not follow up on my multiple phone calls only to sell the vehicle I wanted behind my back. "Legendary Sewell experience" is simply not true. Stay away from this dealership and that person in particular.

This is my third car purchased from Sewell in 16 years, and I will no longer recommend them. I sold my old Yukon to Auto Trader for TWICE what they would pay for it, and when I asked the salesman about the discrepancy in price, he told me that the dealership had to make up cash in the used department because they weren't making enough in the new sales department. A friend of mine bought a car from James Wood in Decatur on June 29th, and his salesman taught him about the wireless features in the car (that he then ... Read More

This is my third car purchased from Sewell in 16 years, and I will no longer recommend them. I sold my old Yukon to Auto Trader for TWICE what they would pay for it, and when I asked the salesman about the discrepancy in price, he told me that the dealership had to make up cash in the used department because they weren't making enough in the new sales department. A friend of mine bought a car from James Wood in Decatur on June 29th, and his salesman taught him about the wireless features in the car (that he then showed me). Even though he bought his car 6 weeks after mine, he received his license plate before me. When I called Sewell about my license plate (now 3 months after purchase), the receptionist told me they had it and did not have a policy of calling anyone to let them know it was there. During the sale, I kept making excuses in my mind for the salesman thinking that perhaps he was inexperienced or that the pandemic had made their lives difficult, but the level of service I have received then and since then, the different times I corrected his mistake assuming it was because he was young and now I wonder if it is part of a change in corporate philosophy has caused me to decide to take the time to write this review. Don't go to Sewell expecting to be treated fairly without having to fight for it as you would with another dealer. If you want to be honesty and a forthcoming dealership where they will call you back and remember the previous conversation they had with you, I would call James Wood in Decatur.

It was an easy and enjoyable experience. The vehicle was as advertised and they delivered the car to our house based on our schedule.

Dropped me like a hot potato. Contacted them via cars.com. They listed 2 2019 XT5 I was interest in. Corresponded with couple folks via email and one guy on the phone. He kept trying to sell me a car I had not looked at and did not want. Long story short I ended up purchasing a 2019 XT5 from Frank Kent on the west side of Fort Worth.

WASTED MY TIME!!! I called Sewell (because of the great reviews) and spoke to a Mr. Oswaldo. I explained to him I was calling about a service bulletin/recall/extended service on a issues with the transmission shifting bad. I gave him the last 8 of the VIN to my wife's 2016 GMC Yukon XL Denali. He stated that the VIN matched a possible problem with the transmission harness. He didn't ask me if there were any faulty codes or check engine lights. Told me to come in and that they would do a complete "diagnostic test". I was just out of work and 20 minutes away. My wife drove 45 minutes from Waxahachie to make it in before they closed at 7 PM. We arrived at 6:45 PM. We met a not so happy to see us, Mr. Bailey. Mr. Bailey's body language told us he wasn't too eager to help us find a solution to our problem from the beginning. I explained to him why we were there. Mr. Bailey began nodding his head and just searched his tablet. Asked if there were any check engine lights and I told him no. Mr. Bailey stated if there are no codes, they can't do anything. We've read hundreds of issues with other GM customers who experience the same issues with no codes. Mr. Bailey asked us a couple of questions about how the vehicle was shifting. Told him that it shifted horribly and reiterated that was the reason why we were there. He asked my wife (mother of our 4 kids) if she drives it aggressively. She responded she drives it normally. His response was, "if you don't drive it like you stole it, it won't shift right". Really Mr. Bailey? GM made these transmissions to shift correctly only if you drive in that unsafe manner? Mr. Bailey continued to state that he has never seen a transmission get rebuilt because of these related issue. For some reason, Mr. Bailey may have been under the impression that I would be impressed on his 20 years of knowledge with these particular issue. I didn't know that they made these 8L90e transmission 20 years ago. Really sir? Mr. Bailey continued to state that GM wouldn't do "sh!+" about it in front of my wife's presence. Unacceptable language in front of the misses. Please keep in mind that during 90% of this conversation he was leaning and resting his elbow on my wife's side view mirror as if he was relaxing at a barbecue. All we came for was a diagnostics and didn't receive anything but wrong information and horrible customer service. We were rushed out of there and were out by 7 PM (closing time). How convenient for Mr. Bailey. No apology from Mr. Bailey. Just walked off without saying a word. WOW! We have to drive 45 minutes back to our hotel and made our week even worse. (My pipes busted in my house during winter storm and under repair. No water) Way better service at Park Place. Mr. Bailey needs to brush up on proper etiquette.

I looked at several vehicles at Sewell, ranging from a 2010 Acadia to a 2017 Enclave. I ended up purchasing my dream vehicle elsewhere simply because it wasn't available on any of Sewell's many lots at the time. However, I can't tell you how awesome and professional the staff here was. On the 2010 my sales guy OFFERED to replace the break pads and provide a second key and key fob on a 9 year old vehicle! I ended up purchasing a 2016 from a different dealer and they wouldn't replace the worn tires of provided a second key. All that ... Read More

This is my first GMC purchase. I purchased my Terrain in Amarillo, TX and shortly after I was experiencing an engine noise, like a knocking noise. I brought my Terrain in several times to the Panhandle dealerships to be dismissed every time. This was so frustrating because the vehicle only had 8,000 mile on it. During Spring Break I decided since I would be in the Dallas area I would drop my Terrain off at Sewell GMC where I was approach by Justin Townsend.

This is my first GMC purchase. I purchased my Terrain in Amarillo, TX and shortly after I was experiencing an engine noise, like a knocking noise. I brought my Terrain in several times to the Panhandle dealerships to be dismissed every time. This was so frustrating because the vehicle only had 8,000 mile on it. During Spring Break I decided since I would be in the Dallas area I would drop my Terrain off at Sewell GMC where I was approach by Justin Townsend. I voiced my concerns and addressed the knocking noise. Mr. Townsend reassured me he would figure out the problem. Mr. Townsend provided me with a loaner vehicle and always made sure I had everything I needed. I ended up taking Sewell GMC's loaner vehicle back to Amarillo while my Terrain was still being fixed. After a few days it was determined that my engine needed to be replaced in my Terrain. Mr. Townsend was more than willing to send his staff on an 8 hour drive to return my Terrain to me and then have his staff drive their loaner vehicle back to Dallas. I have nothing but outstanding things to say about Sewell GMC. The customer service Justin Townsend, Head Technician, and management provided me is truly unheard of. They were prompt, efficient, over the top accommodating and so willing and eager to make this a hassle free experience for me. After this experience I know with the utmost confidence I will continue to take my business to Sewell GMC; and recommend them to everyone I know.
