1974 Ferrari 365 GT4 BB (Berlinetta Boxer)

17885roadItaly
Engine
Flat-12, four overhead camshafts, carburetted

The Ferrari 365 GT4 BB, chassis 17885, is one of just 387 examples of Ferrari's first mid-engined flat-12 road car — the rarest and lightest of the Berlinetta Boxer lineage and predecessor to the Testarossa. Completed in April 1974 and delivered new to the official Swiss importer in Geneva, this matching-numbers example is believed never to have left Switzerland. It was registered to Swiss-based billionaire Bernd Grohe according to a 1980 Ferrari Owner's Club record, and later joined a private Swiss collection.

Are you the owner of this car?

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.
