From works of art and architecture, to products like olive oil and nutella, Italy’s strong cultural heritage means that it is full of things that are iconic and unequivocally Italian.
Although there are a few cars that fall under this category (Ferrari, Maserati, Alfa Romeo) my personal favorite is the Fiat.

Not just any Fiat of course, but the Fiat 500. From the 1950′s to 1970′s, the cinquecento (five hundred) was produced and marketed as a cheap practical town car.
At about ten feet long, it makes the mini cooper look like a full-size sedan – seriously – I saw one here the other day and thought “WOW, that is huge,” which surprised me seeing as how it was the “cute little car” that I wanted in college. But I digress.
