Often, the facelifted saloon version of the 710 model is regarded as a bit of an ugly duckling with it’s notch back and squared off boot but I suspect that’s because most export versions, especially the Datsun 140J and 160J sold in Europe, didn’t get the big tail lights and smooth centre panel like Japanese domestic version, the Nissan Violet. They certainly look pretty good in this Japanese brochure, especially in SSS guise.
The SSS saloon wasn’t sold in Europe as far as I am aware. Like the SSS hardtop, it had independent rear suspension and the Violet SSS-E, got electronic fuel injection as well. Plus there were extras like electric mirrors and an awesome top loading cassette deck! 1976 (Showa 51) also saw the introduction of the Nissan Anti-Pollution System (NAPS) so the 1600 models came equipped with a catalytic converter and evaporative emission controls. These NAPS cars are usually designated as being a 711 model rather than 710.
