The Alfa Romeo 6C 2500 S, often called 'The Last Great Alfa', marks the conclusion of the marque's celebrated six-cylinder lineage dating to 1928. This 1948 example was ordered in late 1947 and delivered new in Spain via importer Ruiz Jimenez, passing to its first owner — a senior Madrid financial figure — who gifted it to his companion. It remained in that original ownership for nearly four decades before changing hands in 1987, subsequently receiving a restoration. The body was found to be largely original, free of rust or accident damage.

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.
