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

Bought my car here and have it serviced here never felt sold very happy with my purchase?the family is loving the new vehicle it rides super smooth

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.

Went in for an oil change?the process was quick and smooth. Really appreciated the excellent service. Big thanks to Elliot for taking care of everything.

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.

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.

Staff was very professional and helpful. Truck was priced as advertised. I received a fair value for my trade in.

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.

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

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.

A very pleasant and help full service writer. They provided necessary repairs in a professional manner. I have been using McKinney Buick since purchase five years ago. I am very satisfied.
