Just checked the great knowledge base that is Wikipedia, maybe i should of said Fiat Seicento aka Fiat 600 1955-1969 model.
ps there is a great picture of the 600/Seicento there.
Since the thread is already a good bit off topic, I think it was Autoexpress that did a "artist's impression" of the latest BMW Mini before it was launched of course, and i really liked it and said i would buy that.
When the Mini was shown, i was very disappointed.
It still surprises me that Fiat didn't explore this potential retro area, same with Renault, I'm sure the R4 would translate well as a retro style exercise.
