New and used 2025 GMC Sierra 1500 Denali Ultimate trucks for sale near McLendon-Chisholm, TX

Excellent care by the entire Ewing team. Special thanks to Jim Bearden for getting me out of there in time for my appointment.

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Simply Exceptional service once again! They continue to be a renowned dealer who cares about their customers and reputation. Sewell will always have my business for life.

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.

Great sales and finance people. No pressure and they did negotiate with me. I highly recommend.

I hate singing the service for an intermittent issue likely caused by a computer chip, on board computer or software but it a serious issue when the Adaptive Cruise control just locks the brakes up at cruising speeds over 55 MPH. I am hopeful they will eventually figure out the issue. This time I requested they just deactivate Adaptive Cruise as I?m worried about serious injury. The last time the brakes locked up out of the blue, I almost lost control of the vehicle and it slide sideways almost flipping at 70 MPH.

I had a great conversation with Kyle Neely, he was very personable and knowledgeable. He made my buying experience fun and easy. He was pleasant to work with.

This was the best car buying experience i ever had! No haggling, no waiting for hours, great salesman, and fast financing. Everything explained thoroughly. I was recommended to this dealer and will recommend to anyone shopping new or used. AAAAAA

I would recommend the Buick dealership. Excellent customer service!

My second vehicle from this dealership. My second Buick Enclave and it keeps getting better.

Great experience from start to finish. Our salesperson, Clayton Haas, was straightforward and efficient, and got us to the price we wanted

They had the vehicle I wanted so it was fast, easy on the paperwork, and I got a good deal. Bruce is an excellent salesperson!

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!

Forest, our sales representative was an amazing man. He was very professional and knowledgeable. He was also very friendly and went out if his way to make sure we knew all about the vehicle we were interested in purchasing. He went with us so I could test drive the car and explained all the features and how to work them . Forest even took me around the dealership and introduced me to various employees, showed me where the service and parts departments were and, once again introduced me to the people in those departments. He also showed me where the customer lounge and vending area was along with the free coffee area. Forest introduced me to the finance person who would be serving me. On a scale of 1 to 10, I would rate Forest a 12. Outstanding! Thank you Forest, Ralph Larry Malone
