It's called "European delivery," and most European car companies offer it.

You go to any dealer here in the USA and order a car the way you like it, there at the dealership. There's usually a discount on the car from the factory for doing European delivery. They also have deals on travel and such.

So you go over there to the factory, go on a tour, etc. They arrange temporary registration and insurance for the duration of your stay. You do some sightseeing or whatever else while driving your brand new car you just picked up for the factory. Then once the trip's over you drop the car off at a port and have it shipped over. One part I'm foggy about is some way that you can avoid taxes or something like that. But I forget exactly how that works.

So that's basically the rundown. You're not buying a Euro-spec car directly from the factory. This is an arrangement that the manufacturers have with their US distributors.
