Where it came from
The Maserati 300S was a racing car produced by Maserati of Italy between 1955 and 1958 to compete in the FIA's World Sportscar Championship. Twenty-six examples were produced.
Under the skin
Power comes from 6 cyl., 3.0 litre (2992cc) in-line engine. It weighs 780 kg. It shifts through a transverse four-speed gearbox. 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 2310 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
In context
Its family tree is legible: it took over from the Maserati 250F; its successor was the Maserati 450S. Its contemporaries in the catalogue — the Mercedes-Benz 300 SL, the Mercedes-Benz S-Class, the Fiat 500 — show what else the money bought that year. Nearby in the Maserati catalogue sit the Maserati 150S and the Maserati 200S.
What it costs now
MotorJury scores cars on the United States complaint and recall record, and the Maserati 300S has none: too old, too rare, or never sold there. Its value today is a collector's question, decided by provenance and condition rather than by a class average.
