Saloon, 4-seater cabriolet/saloon, limousine.

Looks like a '30 Chrysler and semantics are as infuriating as Chrysler's too. Just try your luck at sorting out the 522C (114ins wheelbase), 522L and 524C (121ins) and 524L (127 ins). Later cars have lowered bodies and slanting radiator grilles, 518-style, but everything will have a silent third 'box, X-braced frame, mechanical fuel pump, and dual-circuit hydraulic brakes.
