FIAT 500 (1936-48)
2-seater coupé, 2-seater cabriolet.
The legendary topolino in original form with 13bhp sv engine ahead of its radiator, 12-volt electrics (tiny battery!), gravity feed, four speeds with synchro, transverse-leaf ifs, and quarter-elliptics from mid '38. 50mpg, but two-bearing engine shouldn't be pushed too hard. Rolltop cabriolets commoner than fixed-heads here.
