Yeah, I'm totally wrong. I had assumed the EU tariffs were shared by other nations in the EEA, but it's not true from what I can see. Importing an EU vehicle and US vehicle are the same (except for shipping costs).
Although EU nations, until GF Berlin, aren't quite apples to apples in that regard. But my understanding is that they did final assembly of the S and X in Europe to avoid the tariff, it's only the 3 that suffers.
