Chassis 0581GT is a 1956 Ferrari 250 GT low-roof coupé bodied by the Grugliasco carrozzeria of Mario Felice Boano, one of roughly 68 such cars built through late 1957 and widely regarded as the first series-produced 250 GT road car. Completed in December 1956 and delivered to a Florentine silversmith, it later passed to ATS Automobili co-founder Giorgio Billi, retains its matching original engine per factory records and marque historian Marcel Massini, and has recently emerged from a comprehensive five-year ground-up restoration completed in December 2025.

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.
