The Fiat 508 Balilla began as one of the cars that put Italy on wheels, but the sporting 508S and CS derivatives moved into a different world. The Coppa d’Oro and Mille Miglia versions were small-capacity competition cars, with a four-speed gearbox and a tuned engine, and the Berlinetta Aerodinamica body remains one of the most unusual shapes produced by Fiat’s own special coachbuilding activity before the war. Surviving examples are few, and the model’s appeal is tied as much to eligibility and history as to outright performance.

This 1936 Fiat 508S is listed as a Balilla Coppa d’Oro Aerodinamica, finished in red, with two seats, rear-wheel drive, manual gearbox and 35 hp. The seller describes it as ready for historic events, eligible for the Mille Miglia, with ASI and CSAI homologation and a good sporting record. The listing shows 110,000 km and places the car with a dealer in Montecatini Terme, near Pistoia. The seller has been active in the classic car world for more than 40 years and has a strong reputation, which is relevant for a car where history, identity and documentation carry real weight. From the photographs it appears complete and coherent, but the description is still brief for a car in this price range.

The key checks are therefore documentary rather than cosmetic. Chassis identity, period history, homologation papers, Mille Miglia eligibility, restoration history and the claimed sporting record should all be verified directly. On a car like this, a small difference between a correct, documented 508S Aerodinamica and a later reconstruction or re-bodied car is not a footnote; it is a large part of the value. Mechanical condition also matters, but provenance is the first inspection. Find it for sale at €240,000, approximately $277,600, here⁠ in Montecatini Terme, Italy.
