Easy experience
Julian was a great salesman. Gave me some off on the price, and gave me some extra on the trade-in we had, so I got to the price I was looking for. Genuinely nice dude who was great to work with! I bought a 2019 Ford Explorer because I found their website and it was the best price.
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!

Easiest Car Purchase To Date
I was searching for a new/used car. I used Cars.com to search for a Toyota Highlander. Carmax in Ft. Worth, TX was one of my choices. The car shown online was EXACTLY as shown when I saw it-the pics and details provided about the car were so accurate, there wasn't a need for alot of "wheeling and dealing". I emailed Carmax regarding my interest, late at night. Not only did I receive an email within 1 hour, the next day I received a phone call from Mr. Ben Arbour, the person who would eventually sale me the car. He walked me through their process, got me pre-approved over the phone, so that all that was left to do when I got to the office was to get the trade-in value on the car I was trading, test drive the new car & sign paperwork to purchase. I bought a 2010 Toyota Highlander that was a 1 owner car with approx. 13,700 miles. I recommend Carmax to anyone looking to get another car. They were great!!! The customer service is GREAT!!!
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.

Truck Purchase
Found a 2013 Ram 2500 that was already set up with 5th wheel hitch and more bells and whistles than I could imagine. And at a very fair price. Our salesman, Bill was very knowledgeable about the truck and taught us alot. They are a No Haggle dealership because they are priced right and don't pressure you. We are very happy with them and would do business with them again. The whole experience was positive. All the staff was vary courteous and professional.
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!

AutoNation was excellent it everything they did. They kept me informed and told me exactly what the cost would be. I was also very pleased with final bill. It was not high like I thought it would be. I very much enjoyed working with the service technician that talked with me. I do not hesitate to recommend AutoNation for any car repairs.

Easy process
Worked with Alonso C. in the used car area. Had previously researched the vehicle I wanted (2018 Chrysler Pacifica) and he made the process easy, non-confrontational, and easy. The title guy and I didn't get off on the right foot, but that's probably I intentionally put in a pause to the buying process and had to leave to get my financing from my credit union. Overall I would buy again from this dealership, and Alonso specifically.
