The plate of the Dino is much older than the car. Is the year of its issue identifyable?
Not only the "CH"-sticker shwos, that it was imported from Switzerland, also the size of the plate-holder (black recycling-plastic, so at lest until the late 80ies it ran there) and the missing Belgian fog light.

About the Acura: was where any official export to any European country? AFAIK not.
