Great Experience!
It was such a streamlined process to buy my car. Great salesman and staff — they could not have been better. I went out there only to look but they gave me such a great deal I couldn’t walk away. They never pressured me either. I’m going to recommend to everyone.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

What a outstanding place for to buy a vehicle.
What a outstanding place for to buy a vehicle. I bought a new 2024 Jeep Gladiator Nighthawk. Took test drive, set down with the sales team. Within 2 hours I was driving my new truck home. Usually at a dealership it's a all day adventure but not at autonation jeep north richland hills.

My salesman Craig was GREAT!
My salesman Craig was GREAT!! Would recommend him to anyone looking to purchase a vehicle.. There are some things that could be improved on in the buying experience, ie, the waiting 3+ hours.. I did happen to go on a busy day. The A/C in their building is pretty legit, it was close to 100 degrees that day! Thanks Craig for making my experience a good one...

Mark England is Dedicated! Shop Here
Usually, when you have a bad outcome, people bash the service provider, but not in this case. I wasn't able to get approved without a down payment for a car. But I would like to take out the time and Thank Marcus England from the upmost, for the outstanding customer service, he has been giving me for the past 2 weeks. If you ever need a car, with challenging credit, please contact CarMax Fort worth. Marcus and the fantastic Finance team tried very hard to get me approved. I didn't get a car but the Customer Service shows that CarMax out value in there employees. Thanks so much, I pray Gods Blessings at this place, and that y'all sale 75 cars this weekend.

It started in the service department after I arrived in
It started in the service department after I arrived in my 2019 GMC Sierra 1500 with 175,000+ miles. There was a problem with the transmission. After consulting with a few service techs, I decided it was time to buy a new truck. They introduced me to Thomas Swink in the sales department. He was very knowledgeable about all the trucks and he was an excellent salesman. Not pushy at all, but knows how to close a deal. Negotiations were quick and easy. I was able to drive away that same day in the new truck.
