Nathan was an exceptional sales representative. He went above and beyond to answer all our questions and concerns with the vehicle of interest. He responded in a quick and efficient manner. I would definitely recommend him to anybody looking to buy a vehicle. Especially out-of-state buyers, as we were.

I worked with Steve to find the car I was looking for. He was helpful and easy to talk to. Once I decided on a vehicle, my transaction was very quick to process. I especially appreciated the transparent pricing model they employ with no hidden fees.

We really appreciated the fair pricing and honest work at Red's. After another brakes' shop tried to overprice us on a repair, we took our truck in for a quote at Red's. They gave us an accurate quote in record timing. Super grateful in the way they treated us. Thank you Nick and Justin and the team for saving us money and stress :)
