The 1972 Ferrari 365 GTB/4 'Daytona' (chassis 15437) is a late-production example of Ferrari's celebrated front-engined V-12 grand tourer, originally delivered in Rosso Ferrari over Beige leather to William Harrah's dealership in Reno, Nevada, then retailed to its first private owner in California. Held by two successive California owners for over two decades, it was subsequently exported to Japan before returning to the United States in 2005. The car has received a rebuilt engine by Ferrari specialist Patrick Ottis and a fresh interior retrim.

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.
