If you consider the X5 is assembled in North America, I think it would be naive to think no parts were forthcoming from North American parts manufacturer's. Due to the size of some of these manufacturer's, even if you bought a so called German or European labelled part-it could still well be from a branch of the new world. I replaced a power window mechanism in my X5 with one from Rock. It was ridiculous price structure-it was cheaper to buy the unit with the motor than without-who knew? I always try to buy brand name items when on line, in the case above it was from Dorman. I just ordered a load of sensors for my 540i so we'll see how that goes. Much better price than Autpartsway. I don't know if Autopartsway isn't a branch of the American online vendor Autopartswarehouse- if you go to them they kick you to Autopartsway if they determine you're Canadian. Autopartsway was pretty good at one time they offered free shipping over $75, then $100-now you pay shipping and get higher prices than my local NAPA.
