Very Positive experience.
Very Positive experience. Buying process could have been a little quicker but they also had to evaluate me trade. Ask for Dee Burns. I really enjoyed my experience working with him.
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!

Harry and his team at Lonestar made our trade-in and purchase transfer so smooth and easy. We cannot fault them at all it makes you know you can go back anytime and you won?t get having any issues. We would highly recommend buying or trading vehicles with them.
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.

Great simple oroceds
Rees was my greeter and was an excellent source of information and sales expediter. Rees explained the CarMax process and then Listened to the car features I required. He did searches of car max inventory, searches of manufacturers’ sites for additional info, and requested transfer of a vehicle from another location. There was no pressure to buy (CarMax has a five day return policy). Paperwork was efficient, and I even got help getting both the car I bought and the car I arrived in home. It was my first solo car buying experience so I especially appreciated that I got a car that suited me at a fair price and no hassle
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.

The well coordinated team worked quickly to provide the information necessary so that I could make an informed purchase decision. Representative Kensy was not only knowledgeable but very accommodating. In fact, I was very impressed that she was willing to go into the service area in the high heat in order to lower the vehicle that was on a lift whereby I could look at the interior. Further, her texts and phone calls kept me up-to-date on the progress of the necessary repairs. I noticed the cleanliness of the dealership as well as the positive attitudes of every person I spoke with. Overall, a very pleasant experience. James Simmons Overall, a very pleasant experience. Hey Siri, call Sonya Simmons hey Siri, James Simmons, James Simmons, James Simmons.
