The year that matches the best looks like 1974, but anywhere near could easily be the model year. Not really knowing which is which (and mom doesn't remember exactly either), I picked 1974 as good enough.
The picture below is strictly representative.
I remember ours having a white interior with white vinyl seats. This was the first hatchback that we owned, and the first coup. The idea of popping the seats forward to get in an out was a novelty. Mom's was an automatic. Although the thing looks light, it drove surprisingly heavy by today's standards. Despite its appearance as riding high, the thing wasn't very tippy as its frame was quite heavy.
The interior screamed Japanese design. You see much the same exact design in Japanese cars: center hand brake, bucket seats, padded doors, shifter on the center console, and stiff steering. It was a no-nonsense car in every sense of the word.
In high school, my sister preferred taking this car over dad's larger car, and if she only had dad's car available, would ride with friends, so I didn't drive this car that much once I got my license.
