Drew was there from our first call until we went home
Drew was there from our first call until we went home with a new Chevy. He worked hard to get us where we needed to be financially. Explained everything we needed to know about the vehicle we purchased. Drew was also there for some follow up calls, very patient and kind. We will definitely return for our next vehicle
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!

Staff was very friendly and knowledgeable in helping us
Staff was very friendly and knowledgeable in helping us purchase this vehicle. The buying process was smooth and thorough. We enjoyed the conversation with the Auto Nation employees.
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.

Everyone was great to work with.
Everyone was great to work with. Professional,respectful, courteous and knowledgeable. My salesman Mr. Graver was awesome. He along with the sale manager and finance manager worked with me to give a great deal on the Chevy truck I purchased from them. I recommend Sign It Drive It if you're looking to purchase a great used vehicle.
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!

I had an awesome experience purchasing my car at
I had an awesome experience purchasing my car at AutoNation this past weekend. From start to finish, the process was smooth, stress-free, and very well organized. My sales rep, Ihab, was fantastic, knowledgeable, patient, and genuinely helpful throughout the entire process. He made sure all my questions were answered and never made me feel rushed. The GM was also great and helped make everything feel easy and straightforward, which I really appreciated. To wrap it up, Alexander in finance was excellent. He explained everything clearly, made the paperwork simple, and kept things moving efficiently. Overall, the whole team made this purchase a great experience. Highly recommend AutoNation Plano if you want a smooth and professional car buying process!

Just bought my new 2026 NX350h from Lexus and had an awesome experience with Nicholas Hughes. He made the whole process super chill and easy; really took the time to listen to what I wanted and helped me find the perfect car. No pressure, just solid advice and great customer service. I Definitely recommend Nick if you're thinking about getting a Lexus." Also, a special mention to Greg who helped my cousin and I with great advice on purchasing a car. Thank you both for this wonderful experience.

Was in the market for a new practical vehicle as I lease a new Audi Electric. Wanted something I could jump in and drive, and moving to Texas it was only right I got my first truck. Young Kid Amir showed me two trucks and after two days and giving him a hard time we settled on a 2024 Silverado at a price we could both live with. If you are in the market for a vehicle hit up Amir at Classic Chevy he will take care of you
