Fiat 500C TwinAir Lounge: Road test

The Fiat 500C formula harks back to the 1957 "Nuova 500" styled by Dante Giacosa, which was sold with a full-length retractable roof.

With the green credentials of the new 875cc engine TwinAir engine, can it give the chic 500 21st century relevance? I spent a week with the £15,500 Lounge to find out.
