4-door saloon.

More like an SS, less like a Standard. There was still a 12 engine, but the new 108ins frame had sliding trunnions rather than conventional shackles and the Bendix brakes had gone and were replaced by Girling mechanicals. More importantly, that four door saloon looked so much more modern than the SSII, and the simplified radiator and stylish lines set the SS tone for the rest of the decade. Underpowered and overbodies, it was still good for 70mph, a lot better than many 1½-litre saloons.
