Was very pleased with the experience. Everything was prepared and ready ahead of time. The vehicle was in excellent condition upon arrival except for one detail that was promptly corrected. Mike Willis was easy to work and the paperwork was correct! Everything was streamlined for an efficient experience.

Worked with Mike Willis and it was one of the easiest, most painless and fulfilling car buying processes I have been through. Everyone was genuine, not pushy typical salespeople and supportive in whatever way I was leaning. Will definitely be back in the future!

Mike Willis and all the guys at Red's are Amazing folks, eager to help but not pushy. I honestly think my Vette was slightly over-priced but it didn't matter, I wanted it and the guys made it a smooth transaction. Highly recommended!!!
