To my mind the Tredia also seems to be a victim of the Japanese enthusiasm to cover every conceivable market niche at the time.
The Stanza and Violet are prime examples of cars that are neither in the Escort or Cortina class but slot in the gap between with an odd engine size to boot. To expensive for the person who wants a cheap runabout with a smaller engine, too small for the fleet buyer. Can't immediately bring Toyota's candidate to mind; Tercel perhaps. Honda Quintet and Ballade too of course.
As a result, I imagine the majority were bought by retired private buyers who wore beige cardigans and drove them everywhere at 40 mph. They buy Suzuki Ignis and similar vehicles nowadays - the stuff the makers hoped would appeal to young trendy people but instead always, always are piloted by silver tops for garden centre runs.
The Tredia did sell very well in Austria, especially the Turbo and 4WD-Version! But sadly there are no left because of extreme rust problems. My uncle bought one new in the 80s, a Tredia 1800 GLS 4WD. But after 5 years, it was so badly rusted that it was not safeable anymore. They had absolutely NO rust protection, the Tredia is Mitsubishi´s Alfasud.
Here´s the 4WD, that did sell very well in Austria:
The 4WD-versions were very popular, the Lancer Hatchback 4WD, the Lancer Station 4WD, the Cordia 4WD, the Space Wagon 4WD, the Colt 4WD, the Eclipse 4WD and the Pajero L040 and V20 were the most popular Offroaders in the 80s and 90s. All gone, because of very bad rust protection and long and very snowy and salty winters...
The 4WD-versions had bigger ground clearence because at night, the snow can get very deep on the B- and C-roads until the next plow comes by. Compared to the rare 2WD-versions, it had bigger tyres too.
