Thanks Dackelone. Even me being in EU I didn't visit all this, but I def going to do it when I go buy my BMW and drive slowly for brake-in. I think you can also add the "Musée de l'automobile Schlumpf" in Mulhouse (France, just at the boarder of Germany. It is the town were I studied at the university, because I lived near. There is also a train museum, to which I never went.
The Sclumpf museum is nearly a Bugatti museum, there are alot of them, inculding the Bugatti Royal and the Bugatti Veyron. And then there is the Bugatti factory in Molsheim. I had chance, when I passed there I often saw Veyrons of different colors.
