This latest offering from Superformance, a Southern California company that distributes 1960s-era racecar replicas and continuation models, is a re-creation of a road racer that Corvette patriarch Zora Arkus-Duntov designed in 1962. He planned on a production run of 125 examples, for homologation purposes; his ultimate goal for the car was to win the GT class at the 24 Hours of Le Mans. However, General Motors brass canceled the project after only five cars were completed. Superformance, which is licensed by GM, obtained the original blueprints and molds for chassis number 2 and used them to design its Grand Sport. The company sells the car as a rolling chassis with a coupe body, and the buyer then has an engine and transmission installed.

Engine options range from the iron 350 hp ZZ4 small block to the all-aluminum supercharged and fuel-injected LS9.

You can order the Grand Sport with magnesium wheels like those of the original cars.

Optional amenities include a touring interior, power steering, and air-conditioning.

After canceling plans to produce the Grand Sport, GM ordered that the five prototypes be destroyed. Instead, they were stashed away and survive today.
