Lots of cars to choose from
Hi the dealership is wonderful as the staff are extremely knowledgeable and they have great service, but the only thing that hurts them is the price. The cars are thousands of dollars higher than other place I looked so did not buy from the dealer.
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.
2021 GMC Sierra Denali
This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

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!

It had been 18 years since we purchased a new vehicle for
It had been 18 years since we purchased a new vehicle for our family. My wife and I didn?t know what to expect when we came to AutoNation Ford Arlington on Saturday, April 19. Let?s just say we were both very surprised. � � �We were met outside the entrance by Auday Khirawish. He was pleasant and professional. We have had bad experiences at car dealerships before, but this was not one of them. Auday provided us with the best service that we have experienced in a long time. � � �As we went through the contract, it was time to talk about financing which is not something that most people enjoy when making a large purchase � � �We had already set up our financing with another lender and shared our percentage rate with Kyron Session. As he checked our credit score, he came back to the desk and presented his offer. We were shocked that he offered us almost the same percentage rate. We agreed to his offer and went to his office to finish the paperwork. Kyron was pleasant and personable. It was like we were old friends catching up on our lives. � � �There is a valuable team at AutoNation Ford Arlington. At no time did we feel pressured into buying, even though at the end we did buy our pre owned from AutoNation. We are very pleased with our purchase and the sales team we had.
