1965 Alfa Romeo Giulia GTA

AR 613457racingItaly
Engine
1.57L twin-plug inline-four, twin Weber 45 DCOE14 carburettors, ~150 bhp (racing spec)

Chassis AR 613457 is a 1965 Alfa Romeo GTA homologation racing coupé, one of just 501 built between 1965 and 1969. Delivered new to a Swiss dealership in June 1965, it carries a number of period Autodelta factory competition options suggesting early motorsport use. The car spent its entire subsequent life in Switzerland and then Germany, passing through the hands of noted Alfa Romeo collector Siegfried Otto Hepp among others, and was preserved in essentially unmodified, original-specification condition — retaining its 1965-type 1,600 cc twin-plug engine, close-ratio gearbox, and other period-correct GTA components.

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.
