Every now and then the auction houses give you the chance to own a piece of history. Of course, for the right amount of money! This is exactly the case with this split-window C2 Corvette offered by Mecum. The car is listed as the house's "Main Attraction" and it is expected to be sold for $3,000,000-$3,500,000!

So, what's so special about this C2 Corvette? Well, first of all it is a split-window Corvette race car: it is one of the 14 regular Corvette assigned for competition and one of the two units assigned to Yenko Chevrolet. Secondly, and probably most important, it is "the most successful factory-backed production racing Corvette of the C2 era."

It started with a class win at the first and only Puerto Rico Grand Prix and continued with wins at Daytona, Marlboro, Maryland, Danville, Virginia and Road America.

However, the car itself has a very interesting history. Known as the "Gulf One," this special Corvette C2 was delivered from Yenko Chevrolet directly to Grady Davis, Executive Vice President of Gulf Oil Research and Development.

The package included a fuel-injected 327 CI V-8 engine that delivered a total of 360 horsepower, upgraded brakes, stiffer springs and a four-speed manual transmission.

After its retirement, the "Gulf One" was forgotten somewhere in a barn, and in 1991 it was purchased by noted collector and racer Rich Mason . He paid a fortune for restoration as he wanted the car to be prepared and finished exactly as it was on the starting grid of the 1963 Sebring 12 Hours.

After its restoration, the car won numerous award, including the Best Competition Car at the 2013 Greenwich Concours d’Elegance.

So, what do you think? Does it worth the estimated $3,5 million?
