If you are in the US check the reseller value. From what I've heard it's not holding up at all. Sales are not impressive either. This is what Edmunds had to say:
"Fiat had high hopes for the 500, which was extensively re-engineered for the U.S. and went on sale here in March. The Italian automaker — now the corporate parent of Chrysler — had anticipated it would sell 50,000 Cinquecentos this year in the U.S. Instead, the little hatchback has sold only 17,444 units through November and will likely fall below 20,000 units, according to projections by Edmunds.com.
In December, the 500 received one more bit of bad news — a disappointing overall safety rating of three out of five stars from the National Highway Traffic Safety Administration.
Fiat has made several aggressive moves to bolster its brand image and presence in the American market, replacing its U.S. sales chief in November and hiring celebrity Jennifer Lopez to be its spokeswoman in a series of splashy TV ads."
