Loving this thread and looking forward to posting up mine when it arrives here shortly! Regarding the comments about the black OEM spoilers it's really strange to see those, but obviously in the US market they are arriving that way. In the past 72 hours, the BMW "online builder" has updated itself and is now showing a black spoiler on my build where for several months it had shown a body colored spoiler. Ever the builder itself at bmwusa.com, still says this:

Happy to [almost] be amongst the ranks of you bimmerphiles!
