The Fiat 520 is a 4-door cabriolet / 4-door Sedanca de Ville from Fiat, built from 1921 to 1922, the vintage years, when coachbuilders still shaped most of what was sold. Under the bonnet: 6.8 L V12.
The hardware
Power comes from 6.8 L V12; other versions carried different engines, listed in the specification table below. It weighs 1850 kg. It shifts through a 3-speed manual. The layout matters: a front engine drives the rear wheels, the classic proportion — long bonnet, cabin set back — that most people picture when they picture a sports saloon or a grand tourer. The wheelbase is 386 cm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Family and rivals
Its family tree is legible: its successor was the Fiat 519. Its contemporaries in the catalogue — the Alfa Romeo G1, the Bentley 3 Litre, the British Motor Corporation Austin 12 — show what else the money bought that year. Its Fiat stablemates include the FIAT 702 and the Fiat 1.
What it costs now
There is no federal ownership record for the Fiat 520 — it predates the complaint database or was never sold in the United States — so MotorJury publishes no running-cost figure for it. For a car of this age the price is set by the collector market and the condition of the individual example, not by a formula.
