I told enough in the album about the Fiat 500, a cheap and little car produced in the '60 and '70 in Italy. The daughter of that car was the fiat 126, nearly the same dimensions and power. This was a very cheap and popular car but not like the 500: it was more squared and it hadn't power, I think that the motor was 600 cc or 800 cc, but someone made modifications :
