'Rosso Corsa' (red)

Chassis 15535 is a 1971 Ferrari 365 GTS/4 Daytona Spider built to European left-hand-drive specification — one of only 19 such cars produced, and among nine fitted with a reinforced 'GTS/4-A' chassis. Completed in December 1971 and originally finished in Rosso Dino, it was delivered to Beirut via the official Lebanese Ferrari dealer. The car passed through notable ownership in Lebanon, France, and the Netherlands before a comprehensive restoration in 1999 by Milan specialists. It holds Ferrari Classiche certification, confirming its original engine.

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.
