My 1960 Fiat 500N, alltough it looks like a D it is the last production year of the N, with flat floor in the rear and no real rear seats. But due to the new italian highway codes that came in 1959 it had to get a facelift the last production year! The D was also introduced in 1960, but has room for rear seat passengers feat etc... My car has a 600cc engine from 500R / 126A. And synchronized gearbox from same cars!
