Offered from uninterrupted private ownership since 1975, this 1968 Chevrolet Corvette C3 IMSA wide-body—built by GM engineer/driver Jerry Thompson and driven in-period by Don Yenko—has been recently restored to its authentic Bach–Yenko–Thompson configuration. Campaigned in mid-1970s IMSA endurance events with documented appearances including the Daytona 24 Hours (with Yenko at the wheel) and the Mid-Ohio 5 Hours, the car ran under period numbers such as #17 and #18 and in the distinctive Bach–Yenko–Thompson livery. Documented by an extensive provenance file with Thompson correspondence, period photography and results, Registry of Corvette Race Cars entries, title/DMV paperwork, and a professional appraisal, it has not turned a wheel in competition since its 1970s IMSA career—making this a remarkable opportunity to acquire a unique early wide-body Corvette that is an ideal candidate to be set up for vintage racing (with safety updates to meet current regulations) and a standout addition to any serious collection. Numerous spares are included.
