They were great.
They were great. Very attentive, kept checking in with me. Great dealership. I drag my feet too much. I would recommend them to everyone. Great people working tgere
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Best sales man Mr.
Best sales man Mr. Rawland Long was very dedicated, showed us many cars until we found the one . 100% will recommend to friends and family to come to him THANK YOU!
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Kadin was our salesman and he was so pleasant to work
Kadin was our salesman and he was so pleasant to work with! Great experience! He wasn’t pushy but very patient and so kind. Highly recommend Hiley!!! From the first step on the lot to driving our new Sante Fe home - we were impressed with every part of it!
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Best new car buying experienced I can remember.
Interested in looking at a Grand Highlander Hybrid. Denise Rand was the sales rep. After driving vehicles, it was decided that a Grand Highland was more suited to our needs and we purchased one, Both Denise and Heath Kidder were extremely helpful in the process and a true joy to work with. Employees of this staure are a great asset to this dealership.

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.

I am Very happy with the service I received from Vandergriff Acura Arlington on May 1, 2024. George Hardwick went over and above helping me do an oil change on my 2020 Alfa Romero. He was very pleasant and efficient. He is one of the reasons my wife and I purchased this Alfa Romero and 3 other car from this dealership over the years.
