The best known Prinz model is the 1961 Prinz 4, with its “mini-Corvair” design. But the origins of this small German car go back to 1958, with a first, shorter and more old-fashioned Prinz (3.15 m/124 in. instead of 3.44 m/135 in.). In 1958, the rather similar Prinz II (here) was launched to support the Prinz I, with an engine boosted from 20 to 23 hp and a fully synchronized gearbox.

Collaboration between NSU and Fiat started as soon as 1922. From 1929 to 1957, NSU was devoted to two-wheelers only, and then came back to car production. Fiat- NSU became Fiat-Neckar in 1960. Unveiled in March 1959, the nice-looking Weinsberg was the first original creation of the brand and not just a rebadged Fiat, even if it was based on a Fiat 500. This is a resin model car.
