One of five legendary Chevrolet Corvettes dubbed the “Snake Eaters” is about to go up for grabs.

RM Sotheby’s will put one of the original 1963 Corvette Grand Sports up for bid this weekend at its annual Monterey sales event. The lightweight racecar is considered one of the most coveted versions of Chevy’s most iconic model, which is why it will likely take an eight-figure bid to win this auction.

The car up for auction is the reason why so much fanfare accompanied the debut of the C8 Grand Sport earlier this year. In 1963, the Corvette’s father, Zora Arkus-Duntov, began working secretly on a race car that would be able to best the famed Shelby Cobra. That model, which would eventually be named the Grand Sport, was based on the C2 Sting Ray but featured a more aerodynamic body made of a single piece of thin fiberglass, significantly lighter construction, and a massive V-8. The plan had been to build 125 examples to meet international homologation rules, but Chevy management caught wind of the project and shut it down with just five cars built. Those five would go on to race, though, and are now viewed as some of the most significant factory-built competition Corvettes ever created.
