A 1968 AC 428 Convertible with coachwork by Pietro Frua, chassis number CF25, finished in Guardsman Blue with black interior and dark blue mohair hood. One of only 29 open examples built from a total production run of 70 cars made between 1966 and 1973, this grande routière combines a stretched Cobra MkIII chassis with a 7.0-litre Ford V8. The car spent many years in Peter Black's Yorkshire museum collection before passing to a subsequent private owner who undertook thorough mechanical refurbishment including full engine and gearbox rebuilds.

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.
