I've checked out of curiosity the BMW USA website and wow... you get like ONE FIFTH of the options we have here in Europe... a lot of items missing, at least on the 530e I wanted (Luxury version in alternative to Sport, Panoramic roof, Touring, RSE, Galvanic controls, laser light, several trims and colors like tanzanite blue, active steering of back wheels etc. etc.. so many).
This is what I ordered, if you wanna have an idea at the options available to us europeans (sorry for Italian):

With USA options you can't go too far... with European options it's easy to DOUBLE the cost of the car ahahahaha maybe it's better this way I would have saved a lot of money with USA options only... :P
