This was my second year in a row doing business with
This was my second year in a row doing business with AutoNationUSA-Katy, and it turned out to be even better than the first year. Our salesperson, Jeremiah Ragona, was personable, extremely knowledgeable, and (according to my grandson) even fun to spend time with. The car I ultimately picked to purchase was a bit of an unexpected choice, but one that my wife was quite happy with. Big ups to Jeremiah and the AutoNationUSA-Katy team for a very satifying car-buying experience.

I had the best experience with purchasing at this
I had the best experience with purchasing at this dealership. They are well known for having luxury on a budget vehicles. Financing available, fast & easy, accepted my trade in vehicle and gave me more money than any other dealer offered on the value. My credit is average and I still got a low payment, very nice! Friendly service from Kirk, Andy, & Nida, they make you feel right at home and walk you through the entire process, only taking about a hour of my time. Very efficient this place. Drove off the lot with equity, not a losing value scenario like at a new car dealer. Thank Texas Car Club!!!

I prefer not to go onto dealership and purchase a car, never found it to be a pleasant experience, however this was different. I had an appointment with Jaime Huezo, he had the car bought around for my inspection, settled on a price and the process was over in a matter of minutes. It was the easiest car experience I've experienced.

Once again, Vikki did a fantastic job of taking care of
Once again, Vikki did a fantastic job of taking care of me and my truck. I scheduled the 100K service for my truck, and then got a curveball that made keeping the appointment more of a challenge. Vikki was able to help me reschedule my appointment in a way that still aligned with my schedule. Vikki?s attention to detail, knowledge, and responsiveness give me confidence in services/repairs being done right the first time. Her care and understanding of how to take care of her customers makes DeMontrond the only place where my truck will be serviced.
