A one-off 1964 Chevrolet Corvette Sting Ray built by GM Styling for Chevrolet general manager Semon 'Bunkie' Knudsen, registered internally as GPV-57, this car features a bespoke front end previewing the 1965 production hood and 1967 grille, Du Pont FireFrost Blue coachwork over specially prepared bodywork, and a hand-crafted interior with teak-trimmed steering wheel and white leather seats. Knudsen drove the car daily before passing it on; it was later rescued and restored by a Tennessee collector, and has since been documented in numerous publications.

This car's public record is built from its auction and competition history. Register your ownership and privately add your own records to make it a verified Legacy Metrics passport — provenance that backs your car's value at sale and gives your insurer evidence to price against. Roy reviews and verifies every registration personally.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections. The summary is Legacy Metrics’ own writing; we do not reproduce catalogue text.

“Full” and “partial” documentation labels indicate how well each entry is corroborated in the underlying sources, not an audit of the car’s physical paperwork. Names of recent or living owners are withheld for privacy.
