I life and I'm born in Denmark. I remember back in 1983, a Danish model, "Jeanette Starion", won a model competition(don't remember the name of it). She won a huge money price, plus dozen of price presents, sponsor collectable items. She also won a price car, in which Mitsubishi sponsored. One of the sponsor deals for this competition was, that the model who would go on and win, the models last name would be the new Mitsubishi car name.
The car she won was the new Mitsubishi Stallion(not confirmed back then), but the guy that run the show, pronounced the car in that name to her, and the tv viewers.
They named the car Starion, because of Jeanette Starion won that competition, and that car.
The first from their factory as well. I think you can find search the show on YouTube as well.
