Thank you for helping me with my truck.
Thank you for helping me with my truck. The Grand Prairie Ford dealership refused to accept it and was very rude. I didn't understand why. You helped me without any problem, and the service was always very professional from the first day I called to make an appointment to pick it up. Mr. Mark's service was always friendly and very professional. Thank you so much for everything.
This truck has a jerk when changing gears sometimes.

Awesome help getting car repaired at low cost to m
I bought a used Chrysler 200 from them and did not buy the extended warranty. I just had the warranty that comes with used cars there. Anyway the alternator went out and the Chrysler computer needed reset. The car had to go to Chrysler for that repair. Pricilla was my service advisor and kept me up to date with everything going on with my car. Vandergriff also gave me a loaner car for 3 weeks while my car was being repaired. All I had to pay for was a new battery. I could not have been happier with thier service department.

I dropped of my vehicle. Was greeted in a timely manner. I was given a courtesy ride home. When the vehicle was ready for pick up I was informed. I needed the vehicle delivered given my family's car seat situation so they delivered it to me. Great service..

Had to wait for parts but not the dealers fault. They did a good job in getting a loaner even though this jeep was not purchased from them.

I received an add on Facebook for Hiley GMC Buick of Ft
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!
