Chassis 14397 is a right-hand drive 1971 Ferrari 365 GTB/4 Berlinetta that was converted to Spyder configuration in 1978 by CP Autokraft, with body dimensions taken from a genuine factory Spyder. Delivered new in the UK to its first owner via Maranello Concessionaires, the car passed through several notable British owners before spending time in Australia, and returned to the UK in 2013. Repainted to its original red with black leather, it is regarded as among the best-known Daytona conversions in Britain.

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.

“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.
