To run in the World Challenge GT top ten it takes $25K to $30K per race and a good driver. The fact that GM has spent millions backing Caddy and hiring some of the best drivers they can get and is still losing to Dodge speaks volumes about Viper performance and durability. I don't know of any hired guns driving Vipers in WCGT. All are owner-drivers I believe. No need for factory sponsorship when your product does well on it's own.

SCCA T1 are the street cars we can buy off the showrooms, add the required safety equipment and go wheel-to-wheel. Even though technically they are amateurs the front-runners would be respectable in WC GT.
