I bought a 1994 C4 Corvette from Keystone Corvettes two years ago and was completely satisfied with the experience. The owner, Joe Shields, is as honest a businessman as I've ever met. When there were minor issues with the C4, he went out of his way to solve the problems and ensure my satisfaction. He once even brought his truck to my house, 90 minutes away from his dealership, and took the Vette back to his garage to work on it without charging me for the transportation. If a problem comes up that he can't solve, he'll find someone who can deal with it. He has years of experience with Corvettes and knocks some of the quirks of each generation. I've been so happy with Joe that I recently traded in the C4 and purchased a 2004 C5 from him. Joe offers high-quality cars for sale and backs up what he sells. If you're in the market for a Corvette, it would be hard to do better.
