Even though the regular tin-topped Fiat 500 subcompact is still creeping onto American roads, its makers are confident enough to introduce a cabriolet version, the ’12 500c. From the drivetrain aspect, there’s still a 101-hp 1.4-liter four connected to either a five-speed manual or a six-speed automatic transmission. In Pop trim, the 500c starts at $20,000. The swisher Lounge trim goes from $24,000, and there are plenty of personalization options for either version.
