Why it matters

The C12 was Callaway's most heavily reworked Corvette: a C5-based car with new carbon fibre, Kevlar and fibreglass bodywork and a revised chassis, developed jointly with the German firm IVM. It was so far removed from the production Corvette that cars sent to Europe were titled as Callaways.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

Callaway Cars was founded by Reeves Callaway in 1977 and began selling modified Corvettes through Chevrolet dealers in 1987. The C12 was introduced in 1998 as a bespoke high-performance car with a civilised interior and relaxed ride, designed and built with IVM in Germany.

Most cars were custom-made to the buyer's specification, so individual examples differ in transmission, brakes and trim. One auction example, a C12 Speedster, was among only two convertibles built with a 4-speed automatic. Production numbers are reported as about 19 or 20.

Identification guide

How to tell an original from a replica or later conversion.

The C12 carries the same serial number format as a standard Corvette. Under the body it shares only the glass, door cut lines, door handles and removable roof panel with the C5. The bodywork is carbon fibre and Kevlar, made by IVM.
