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.

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!

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!

I've been going to this dealer for the 6 years I've had my Buick. Mary was outstanding and a great employee. Great experience again!

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

Service was very good. It exceeded all expectations, which were very high to start with. I was met right away at my door and was walked through the whole process. Even on the pick up , I was greeted at the door and helped until I left. I apologize for not responding earlier.

My service rep was Brandon was on lunch when I came in. He made sure to come find me and introduce himself on his return from lunch. He was very communicative and ensured I was satisfied with the service and treatment received

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.

Great service nice people clean environment Thanks to everyone over at Ed Morese thank you for all your help I will be telling friends about the great experience

I wanted to purchase a new vehicle and Terry was the sales man who also sold my mom a car his kindness and understanding made me me feel comfortable. His customer service was spectacular. The finance person was also so kind. I will recommend this dealership to others. They know how to make their customers feel valued.

We had a straightforward, no hassle, seamless car buying experience at Ewing. Our salesman, Clayton, made the entire process easy for us from trading in our ?problem vehicle? to finding us the exact car we were looking for and having it delivered promptly. There were no salesman tricks, no hidden fees and no pushes to purchase extras we didn?t need. All around great experience. Highly recommend!
