Datsun Bluebird SSS coupe rear quarter
This was known as Bluebird in Japan and 510 in the US. Eventually when it's ostensible replacement, the larger 180B/610/Bluebird U, was released the old series body continued in production to ultimately be replaced with the Violet/140J/160J models, not sold (but rallied!) in Australia.
The SSS model (coupe only?) had a special engine. The independant rear suspension was a new addition to the 510 model design.
