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

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.

I have had many Jeeps, when they stopped making the Cherokee I was at a loss until I came upon the GMC Terrain and so happy I did. Great style, performance handles great, many exceptional features, I spend a lot of time driving and never feel like it is tiring, lots of room in cabin and the cargo area. I have a new favorite, and it is the Terrain

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’m 56 and I’ve mostly owned trucks in my life. Out of the few cars that I’ve owned this 26 terrain elevation edition is the best car that I’ve owned. It’s comfortable and expensive gets good gas mileage plenty of room inside well designedand GMC has been a reliable brand for me over the years. I do recommend this car.

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

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.

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.

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