I'm not sure the German factory is making them for the UK market, the Performance isn't released in the UK (I don't think) and for some reason UK gets LR Y's from Shanghai (when we don't).
In the end I don't care (although the German built cars are meant to have better suspension, better paint and now the better, like way better, seats) it is starting to add up the differences whereby the German built's Y's are vastly better.
I really do want to wait for the better seats, comparing my Model 3 Performance White seats to my wife's Model X...the X has SOOO much better seats...the new look seats on the German built Y look much closer to S/X seats, IMHO a huge improvement.
