Chassis 6318 is the 104th of 125 first-series Lamborghini 400GT Isleros built, completed at the Sant'Agata factory on 11 November 1968 in Argento silver over tobacco leather — the colour combination it retains today. Delivered through Milanese concessionaire Auto Elite to its first owner in the Como region, it subsequently passed through British and American ownership before a comprehensive mechanical and cosmetic overhaul in 2011–2012, after which it placed third in class at the 2012 Concorso Italiano.

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.
