ALVIS FIREFLY 12

Sports tourer, drophead coupé, 4-light saloon, 6-light saloon.

Junior relation of Speed 20 with flat instead of vee radiator: unfortunately chassis is scaled down SA, too, and a 50bhp single-carburettor 1½-litre four can't really cope. Central change and unit 'box now general Alvis practice, though some Fireflys have pre-selectors (avoid). Open ones can still make good money, none the less.
