They did it all, the experience speaks for itself,
They did it all, the experience speaks for itself, perfection, only way it could have been better is if it was closer to my house and free, thank you much!
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

They are reliable, honest and operate with integrity.
They are reliable, honest and operate with integrity. I recommend them to anyone who is looking for a reliable car . Darrell always takes the time to answer any questions I may have, and provides me with all the options. As a woman, it can be difficult to find a salesperson you can trust l'm very happy to have been referred to autos of Dallas!! Darrell was the best!!

The Beset of the Best
The level of care, kindness, and respect that Tyler Reynolds showed to my wife and I was unlike anything we have experienced at any dealership. Every other person of the Sewell staff was no different. I have always heard great things about Sewell dealerships and we were not disappointed. We worked with Matthew Jobe on the finance end and he was fantastic as well. Both Tyler and Matthew from start to finish provided us a true no pressure deal. I’m convinced that Sewell Buick GMC wants what’s best for my family and budget. It almost feels wrong to say that I really enjoyed the car buying experience at a dealership but it’s the truth. I want to make sure and add that the care and help did not stop when I drove off the lot. Tyler and Matthew have answered every question quickly and professionally since we have had the car. All that being said, my family will never buy from another dealership. These two men have made us Sewell customers for life.
