The Fiat 500. This is one of the smallest cars in the world. The Fiat 500 was created just after World War II by Fiat, the Italian car company. It quickly became the symbol of reconstruction, and of the freedom held by the Italians during the economic boom of the 1960âs. Today many amateur associations have brought together the enthusiasts of this small car, and itâs not unusual to spot them driving along the Sicilian streets and through the small villages â an interesting and amusing symbol of Italian culture.
