Actually, it was done first as a concept car, then the race version was done just to exam the possibilities. This had the Vette folks in a twit, but The Deuce pulled the plug on all racing programs, essentially killing the Mach !! project. It was revived later when Bunkie became the CEO and the Screeming Yellow Zonker (Larry Shinoda) built a concept car in his studio. The Deuce invervened again and out the door went Bunkie and Larry.
