at least if it is the car I am thinking of lol
I am sure Mercury were also thinking the same when naming it
But some companies do use names in Europe (Ford, Toyota, Nissan, Honda, VW, Renault, to name a few), and other than the Beetle, you've consistently chosen models sold on one side of the Atlantic and not the other. So perhaps the complaint of being US-centric is somewhat justified in this case.
Only one time I have seen a car with a number, and I remember cause I thought it was odd that it didnt have a name, it it when for my graduationday my boyfriend lend a very fancy sportscar. A mazda.. mx6 or something, let me look it up.Well mx-5 exists so that might ve been it.
One advantage in some cases is that the numbers give you a clue on the car size or newer model.
