Chassis 2505 GT is the 18th of just 56 Ferrari 250 GT SWB California Spiders produced, and notably only the fourth of sixteen examples delivered with uncovered headlights. Completed at the factory in July 1961 and originally supplied to the official Milan Ferrari dealership, this European-delivery car spent over a decade in Italy before passing to a long-term Swiss owner. It later received a comprehensive, numbers-matching restoration by Ferrari Classiche in Maranello, earning Ferrari Classiche certification and a Platinum award at the 2011 Cavallino Classic, and was subsequently displayed at the Museo Ferrari.

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.
