First time customer in Dallas, Tx
For some reason Mark's name is not on the list where it says, "Choose their name," but Mark was so helpful, patient, explained the process clearly and was very professional. I highly recommend him and would work with him and his team again. I would hope for a promotion for him Hyundai. :)

I sold my car to this dealership.
I sold my car to this dealership. They gave me the best price, but more importantly, the service was just exceptional! Samantha and Graham are the best. I?ve never experienced such honesty, integrity, and compassion at a car dealership in my life. 10 stars if I could!

Best Car Buying Experience Ever!!
Jose the Sales Manager listened to what I wanted and found the vehicle at another dealership and brought it over. Briana in Sales showed me all the features and explained how everything works. She even helped me get the app set up on my phone. David in Finance was so friendly and made the process easy. I have told all my friends how nice everybody was to me and this was really a no-stress day. I love them. I wish I could buy a new vehicle every year so I can go back over and over.

Great Customer Service
Our sales person Samuel was accommodating, helpful, made sure we knew all of our options, and made the process so much easier. Sheryl in the back office where I signed all of the new owner paperwork and forms made it so much fun! Great staff. I came there to get a used car because my husband had such a great experience there last year getting his car.

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!

Overall, Vandergriff Chevrolet service dept.
Overall, Vandergriff Chevrolet service dept. did an excellent job on my repair. With an extended warranty, the repairs cost nothing. But if I do critique anything, is the trying to get me to spend $1,200 in new battery cables. There was nothing wrong with them.

Overall good experience. Couldn’t get much done until you go in. Only put half a tank of gas in after they said they would fill it up and no floor mats. And manager special is not for everyone.

We just bought a used car from HILEY- Buick- GMC-of-Fort
We just bought a used car from HILEY- Buick- GMC-of-Fort Worth with John Talley. We had shopped extensively and found good deals at 3 different dealerships. Although one of the other dealership's offer was slightly better than Hiley's, we were completely swayed by John's knowledge, experience, and trustworthiness. We liked everyone we met at Hiley, but out of all the salepeople we met at all of the dealers in west Fort Worth. John Talley is the main reason we bought the car we did. And then Ron and Taylor in Finance made us glad John was at Hiley (they give Finance people a good name!}.
