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. Rachel was amazing, Robert her manager did a wonderful job managing the process. Thank you Rachel!

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. 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.

They make you feel like family. My experience with Tyler Ramirez has been great. My purchase was easy and the care after has been great

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.

Wasted my time contacting Sewell who said all denali xl were sold before arrived. Same story at all other dealers advertised by cars.com

Just like the TV ads, the focus is the customer 100% Super honest, zero pressure, instead great communication and updates/

Bought a car recently from there and found out the hood scratches badly but dealer didn’t tell you. I thought it was dirty and can be removed but couldn’t not. I disappointed

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.
