Buying from Tommie Vaughn was a great experience overall.
Buying from Tommie Vaughn was a great experience overall. Omar was a huge pleasure to work with. Definitely coming back!!
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!

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.

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.
Best truck we have owned!
Truck meets my and my wife's needs. She loves her and I do to! Love sport mode and the tow hail mode. Rides like a Cadillac!

The best car dealership in Texas!
This has to be the best car dealer I ever bought a car from. I was in the market for a 2022 Jeep Wrangler Sahara, and I saw the vehicle I wanted to buy from their website. I called this dealer, and spoke to Jaime Marroquin, their internet manager and my salesman. He explained to me the process of securing this vehicle since I live in San Antonio. A few days later, my girlfriend and I flew to Houston, and Mr. Marroquin took the extra step to pick us up from the airport. Everyone at the dealership, from the manager, finance staff, and others, greeted and treated us as if we were important. We were done and driving back to San Antonio in a little over an hour. I will be back in the near future to buy my next car from them! They deserve 10 stars instead of 5!!!
