The "father of the Corvette" Zora Arkus-Duntov initated a project in 1962 to create a lightweight Corvette that would be able to beat the Shelby Cobra on any given race track. He was going to build 125 of them in order to homologate the car, but he never cleared the project with GM's executives, and the project was shut down after building only five cars. Today, these five are all in private collections and are estimated to be worth $6 to $8 million.
