One of just four with this crazy exhaust system was built for Chevrolet Division general manager.
Chevy made a lot of noise back in 1963 with its New York Auto Show Corvette Stingray convertible concept. So much so, that general manager Semon "Bunkie" Knudsen had Chevrolet Engineering build a special example just for his personal use. Knudsen's bespoke Corvette was given a special side exhaust and custom paint job, in addition to a white soft top and full-length race stripe. The interior was also modified, with new seats, door panels, brass trim and more.
Underhood, the 327 CI small block V8 was modified for the special exhaust, and joined Nova, Corvair and Impala convertibles as one of Bunkie's daily drives. It was later found in disrepair in the 1980s, and restored by a dedicated collector. After several additional owners and restorations, it was put on display at the National Corvette Museum and other collections for several years, including the 2012 Amelia Island Concours d'Elegance. It will be up for Auction at the Mecum Houston 2014 auction on April 12.
