New and used 2025 GMC Terrain SUVs for sale near Lucas, TX

They say the most loyal customers come from ones who have an issue and the company makes it right, even if it wasn?t their fault. This couldn?t be more true with the service department at McKinney GMC. They took an issue that was not their fault, and fought alongside us to get it rectified and ensure a positive outcome for us and I will be forever grateful for John, Rob, Amanda, Caleb, and Victor for putting in the extra work to help get this resolved successfully. We just picked up our vehicle after it being in service for 5 months, to no fault of the dealership, but due to an issue with the insurance adjuster. Our vehicle had shut down due to what was later determined to be contaminated fuel, but the insurance adjuster made a mistake in his findings, and denied it. The service department answered every question, provided every document, picture, and detail I requested as I was fighting this with insurance, and let me tell you, I requested a lot. And they did it with grace, even on the days I sat in their dealership for hours on end collecting things. We had also contacted GMC/GM customer service and the McKinney service department did all they could to work with them, and helped us to have the claim resubmitted to insurance. After a long and painful process, we finally have our vehicle back, insurance rightfully covered the work, all because of the dedication of this team. McKinney GMC will have a customer for life in me. Thank you again team for all you did!

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

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.

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!

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.

I would recommend the Buick dealership. Excellent customer service!

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.

Rachel scheduled my appointment and was very courteous while checking me in and upon my departure. The technician did a great job of diagnosing my problem and getting it. Corrected

Wendy did not ask me to write a review but I do want to mention her because she helped us out in a relaxed, motherly manner. I feel she did more than necessary which was sweet. The steps and processes of our 2 trade-ins for a pre-owned vehicle also happened pretty quickly and without issues on their end. Great company. Would return.
