The 1978 Corvette

1978 Anniversay Edition Corvette Ad

1978 was the 25th anniversary of Corvette. To celebrate a competely re-designed body was rolled out with new "fastback" styling. The new wrap-around rear window provided much more space behind the seats but was not a hatchback. Access to the storage space is still accessed from behind the seats. All Corvettes this year came with special 25th anniversay badging. A special "Anniversay Edition" included a unique Charcoal Silver/Silver Metallic two-tone paint job for an extra $399. Production of the anniversay edition was not limited and 15,283 Corvettes were eventually sold with this paint. The 1978 Corvette was the pace car for the Indy 500. Chevrolet created a limited edition pace car replica, this option added over $13,000 to the price of the car (more than the base price!). This car has distinctive Black/Silver two-tone paint with a red pin-stripe. Production of the pace car replica was limited to one for every Chevrolet dealership. This amounted to 6,502 pace cars built in 1978. All '78 Corvettes were built with Rochester Q-Jet carburetors.
