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

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.

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

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.

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.

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.

Jarrett Abel has been my Service Adviser for several years. He always takes care of scheduling my appointments and getting my Chevy P/U serviced. The service department does a terrific job of getting vehicles serviced quickly.

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.

All staff are kind and professional. The facility is clean and welcoming. I love the shuttle they offer to take you to and from your home.

Very good and courteous staff. Had difficulty locating my appointment but all went smoothly afterwards. Picked up my car in no time. It is always washed for me!
