1951 Siata 300 BC Barchetta

ST 418 BCroadItaly
Engine
1.1L inline-four OHV Fiat unit, single Weber carburetor, approx. 51 bhp
Colour
Italian red ('Rosso')

Chassis ST 418 BC is the 18th of roughly 40 Bertone-bodied Siata 300 BC Barchettas produced between 1951 and the early 1950s, fitted with a tuned Fiat 1100 motor whose number matches the chassis. Originally owned by racing enthusiast Bob McNeal and occasionally driven in competition by Ron Hunter, the car passed through several American hands before receiving a full restoration by noted 300 BC authority Jarl de Boer in the mid-1980s, including a repaint to Rosso and preparation for historic racing. It has been in extended climate-controlled storage for approximately three decades.

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.
