The rag-top model has been uncovered by the company's US arm - where it's set to be known as the 1957 Edition - and the 500C model harks back to the roll-back roof top of the original Cinquecento.
Styling changes for the Vintage '57 Edition include colour-coded wheels, which are 16-inch forged aluminium four-slotters complemented by big chrome hubcaps that bear the old Fiat logo, chrome exterior trim highlights, and new colour options such as Verde Chiaro (pictured top) and the powdery Celeste blue (below).
The interiors of the 500 and 500C Vintage '57 Editions feature two-tone Marrone and Avorio (brown and ivory) leather trim.
Under the bonnet of the versions sold in the US is a 1.4-litre four-cylinder engine with a five-speed manual or six-speed automatic.
Fiat's Australian arm has told CarAdvice in the past that it is interested in adding the 1957 Edition to its local 500 line-up, and sources have indicated to us that the brand would love to offer both the hard-top and soft-top versions of its top-selling model if they were to be made available.
