If you’ve never heard of the MarDal, that’s because it was a bespoke one-off—its name formed from Marzotto + Dal Moro—commissioned by the racing Marzotto brothers, especially Umberto, in 1951. The brief was pure post-war Italian ingenuity: a petite 750 built on a lightweight Gilco tubular chassis (the same firm that supplied Ferrari’s racing frames), powered by a tuned Giannini engine, and clothed by Carrozzeria Fontana of Padua, a coachbuilder known for personalizing Ferraris. The car debuted with motorcycle-style cycle fenders; when regulations changed for 1952 and required fenders attached to the body, the design was updated accordingly.

Ready in 1951 for its impatient owner Umberto Marzotto, the MarDal went straight to the road courses that defined the era. It ran the Giro di Sicilia, made its first Mille Miglia appearance in 1952, and later returned to major historic and national events—including outings in 1977 and 1984, the Coppa d’Oro delle Dolomiti, the Monza circuit, and more—building a rich and eclectic palmarès over decades.

Mechanically, the car retains its original 750cc single-overhead-cam Giannini unit, which in 1954 was replaced with a Giannini 1.0-liter twin-cam to stay competitive—an evolution typical of serious sports specials of the period. Today it comes with period plates and registration, ASI and FIVA paperwork, and substantial historical documentation, making it Mille Miglia-eligible. In a single machine you get a featherweight Gilco frame, hot-blooded Giannini engineering, Fontana’s artisanal aluminum, and the Marzotto family’s racing drive—a compact time capsule from the most romantic years of Italian motorsport. Last but not least, the car is featured in this video. Find it for sale at €430,000 (today $497,000) here in Isso, Italy.
