One more - how about a whole rebody ?
FSO (Poland) is one of those companies that took old FIAT 124/125 models of the 1960s to make as their own - in the style of Lada, amongst others.
Like Lada they kept then in production for ages eventually rebodying them into the Caro.

Designed by Giugiaro no less. Obviously he had a cold that day.
