Had a great experience at AutoNation USA in Denton.
Had a great experience at AutoNation USA in Denton. Met with Cody and his Sales Manager, Sam, and both were super helpful and easy to work with. Went in looking for a safe, reliable SUV for my family, and found the perfect one. I had been checking out similar cars at other dealerships, but I kept coming back to AutoNation because they had the exact color combo I wanted inside and out. The SUV drives great, the price was fair, and the whole process was straightforward. Cody and Sam were transparent the entire time and walked me through each step without any pressure. They kept their word the whole way, which I really appreciated. I?d definitely buy from AutoNation again and recommend them to anyone looking for a solid, reliable vehicle.

WOW, I was pleasantly surprised by the outstanding
WOW, I was pleasantly surprised by the outstanding customer service I received from this dealership. I had initially thought it was a big-name dealership that would pressure me into getting a co-signer or putting down a large down payment. However, I was pleasantly surprised by the friendly and helpful staff, especially Lori and John. Lori went above and beyond to help me buy the car I was eyeing with a not so high down payment. I truly appreciate the effort and dedication they put into making my purchase a smooth and hassle-free experience. No co-signer was required, and the down payment was manageable.

Was in the market for a new practical vehicle as I lease
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

My experience at this dealership was great!
My experience at this dealership was great! Garret was my salesperson and he was very experienced and did a great job helping with my car purchase. He gave me the keys and I knew it was the one. I test drove the car and it drove perfectly. The tires looked pretty new and the inside had no damage. The cars on their lot are very clean and maintained. Sam was who I worked with on the financing and he was very thorough in explaining all the options that I had. All the people there that I met were very nice and friendly. I would definitely recommend this car dealership.
