1963 Chevrolet Corvette Sting Ray Bunkie Knudsen Convertible

Publish date: 2024-07-06

Closely patterned after the famous 1963 Sting Ray convertible built by GM for retired styling chief Harley Earl, this equally rare convertible was presented to Chevrolet Motor Division president Semon “Bunkie” Knudson. Finished in Rose Pearl with a full-length White racing stripe, it is outwardly distinguished by its chromed header-style pipes. The interior shares the unique upholstery, grated foot-well plates and custom color scheme as the Earl Corvette, and boasts a specially finished fuel-injected 327CI small block.
