Truck needed regular service and found out it also needed
Truck needed regular service and found out it also needed the fuel filter replacement, service rep. Edgar communicated this to me and I went ahead approved the replacement. The whole service process including fuel filter replacement took a lot less than I expected, Thanks!...

The Beset of the Best
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.

Wendy did not ask me to write a review but I do want to
Wendy did not ask me to write a review but I do want to mention her because she helped us out in a relaxed, motherly manner. I feel she did more than necessary which was sweet. The steps and processes of our 2 trade-ins for a pre-owned vehicle also happened pretty quickly and without issues on their end. Great company. Would return.

I hate singing the service for an intermittent issue
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 received an add on Facebook for Hiley GMC Buick of Ft Worth. I had been looking locally in Lubbock Texas. While looking at their on-line inventory, I noted that several models had fantastic discounts and rebates. I couldn't get anywhere near these advertised prices in Lubbock and the saving was more than enough to warrant a trip to look in person. Brenden was so helpful before the trip and accommodating in person. Long story made short; buy from. Hiley and ask for Brenden. They'll treat you right!

Forest, our sales representative was an amazing man.
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
