Siata - Siata Amica 600
The Siata Amica was available from 1956, with two door convertible bodywork, having the Fiat 600 633cc engine and later a 735cc. Amica production went to 1968.
Siata Amica tyre size was originally a crossply 5.20x12 but the radial ply 125R12 is a good substitute - see details below:
