1966 corvette
Despite its popularity, the second-gen Corvette holds the record for the fewest number of production years of any generation Corvette. The most valuable examples of the C2 Corvette live sort of like "bookends" at the start and finish of second-gen production.
When one of his cars was severely damaged in 1972, John Greenwood converted his 1969 L88 Convertible into a formidable race car. Included as the formidable ZL1 engine with 750 bhp on tap. Other modifications included a rear spoiler, quick replacement radiator and camber adjusters. At Le Mans, this car set the GT-class record for top speed down the Le Mans straight with 215 mph.
