A 1930 Alfa Romeo 6C 1750 Gran Turismo of the fourth series, first registered in London in May 1930 and remaining in the United Kingdom throughout its life. Restored in the early 1980s by noted pre-war Alfa racer Rodney Felton, the car was fitted at that time with handbuilt aluminium Zagato-style Spider coachwork and rebuilt to Gran Sport specification with a period supercharger. The original chassis and matching-numbers engine are retained, and the car has been recently recommissioned for active use.

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.
