Excerpt from "Impact '66" promotional film. Good quality, interesting. It was fun watching them wring out the Corvette and it was interesting to see that in '66 Chevrolet was still happy to promote 4 door performance (396 vs 409, Novas, Corvair, etc)-it definitely didn't have the stigma that more-doors received from enthusiasts in later years.
