The Alfa Romeo GTA was a lightweight homologation special produced in the mid-1960s, combining alloy bodywork by Bertone with a 1,570-cc twin-cam four-cylinder engine to achieve a kerb weight of around 740 kg. This example, finished in red over black, was delivered new to Switzerland in December 1966 and subsequently passed through several Italian owners. It later entered the Mario Pietrella collection, where it received a concours-level restoration to Stradale specification, including period-correct Weber carburettors and select Autodelta components.

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.
