This is our third car purchase with Red's and our second with Mike Willis! Mike was very patient with our wandering between 6-8 vehicles on the lot and settling on 2 to test drive. Very knowledgeable about the Lexus we settled on. Great purchasing experience and highly recommend!

Transparent and honest. Gave me a great deal on my daughters first car. I gave them my budget and they called me when they found exactly what worked for me. I would buy from them again.

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.
