First built in 1955 by Zastava in Serbia, the 750 was a "supermini" class of vehicle based on the Fiat 600. The tiny two-door city car has its engine at the rear and powers the rear wheels with about 30hp. Although it was given a bigger engine in 1960 and the designation 850, the vehicle's exterior design remained virtually unchanged from that of the Fiat 600. Throughout its life, the Zastava 750 had just a few minor revisions until being discontinued in 1985.
