New and used 2026 GMC Terrain for sale near Garland, TX

The Dealership was great to work with from my initial contact through the buying process. They took about a hour training me on all the features of the car. Their follow-up asking me how I like was an added touch.

This is a very beautifu vehicle, very dependable but the gas mileage could be better. With all of the new technology, it is somewhat difficult to remember all of the various control panel options. Also the owner’s manual is very skimpy.

Wonderful people. Kind & very knowledgble. Would recommend them to anybody.

Had a great experience there hassle free. Jermey Burrell had everything laid out for me when we got there. I would recommend to anyone. Keep up the nice work.

Jeremy was incredible and made the process of buying a new car so easy. When it’s time for a new car, he will be my go to salesman.

Robbie, my salesman, was outstanding!! He made it painless and is absolutely customer focused. Pricing was ultra-competitive. Dealership was clean. We will definitely go back.

Absolutely phenomenal experience at McKinney Buick GMC, all thanks to Derek! From the moment I walked in, he made the entire car-buying process seamless, stress-free, and enjoyable. Derek?s professionalism, knowledge, and genuine care for his customers are unmatched. He took the time to understand exactly what I was looking for and made sure I got the best deal possible. There was never any pressure?just honest guidance and top-tier customer service. He went above and beyond to ensure every detail was taken care of, making this the best car-buying experience I have ever had. If you?re in the market for a vehicle, do yourself a favor and ask for Derek. You won?t be disappointed! I cannot recommend him enough and will definitely be sending friends and family his way. Thank you, Derek, for setting the gold standard in customer service!

Several sales personal where informative and knowledgeable in customer service. I didn’t purchase a vehicle but will give Vanguard the first choice at sales.

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.
