Red’s Auto and Salesman Nathan Warner were incredible! They helped us find the perfect car. They listened to our needs and understood what we wanted. Paperwork was fast and efficient. They had an amazing selection of cars, especially electric cars (which we bought). I will definitely buy from them again.

I’m from Massachusetts and bought a 2007 C6 Z06 one of my dream cars with the guys at Red’s Auto and Truck and they were very easy to work with and great people overall.

This has been the most painless used car purchase that I have ever had. Mike Willis, my salesman, responded quickly to my inquiries and there were no hidden fees in this purchase. The vehicle, a 2015 Lexus RC350, is in excellent condition and Mike made sure that I was well aware of any issues, dings, dents, scratches, etc. before I even drove the 8 hours to pick it up. I would buy from Red's again with no hesitation!
