The Fiat 500C is one of the auto industry's smallest convertibles. Based on the
Fiat 500 hatchback, it gets a unique convertible top inspired by the classic 500 that slides back more like a large sunroof than a traditional fabric roof. The 500C shares its charming retro styling with the hatchback model. Fiat does a high-performance Abarth version, too, with the open-air top making it easier to hear the car's big-attitude engine.
