Fiat 500
Fiat 500 

Something of an Italian answer to the VW Beetle, the original Fiat 500 was produced from 1957 through 1975 and featured a rear-mounted, air-cooled engine of just 500cc (a half-liter) in size. Among the 500's (or Cinquecento's) lovable traits were its diminutive yet space-efficient body that made maneuvering in crowded European cities a snap, an available large fold-back canvas sunroof and a small appetite for fuel.
