Loved my whole experience at CARMAX, Fort Worth!
My brother-in-law recommended that I check out car max when needing to purchase a good used car. First I went on line to see what cars were available. I found exactly what I wanted, in my budget, at the Plano location. Luis Delatorre, my fabulous agent, at the Fort Worth, River Ranch Blvd., had the car transported to Fort Worth and I purchased it on sight! I Drove it around the block, and had all the paperwork efficiently delivered to me within 30 minutes! I've found my future dealership and will recommend Car Max to anyone who will listen to me!
This truck has a jerk when changing gears sometimes.

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.
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’m looking and have been for a while. I have found most car sells men don’t care what they say to sell a car. I was pleasantly impressed with a young man by the name of Luke Fox when showed me the cars and all that entails. When I make my final I hope I can buy it from Mr Fox. Thank you Luke

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.
