There are Sport editions available in Carbon Black now in Europe I know and probably other areas. They came out about 3 months ago and had the blue stitching on the seats.
http://www.1addicts.com/forums/showt...=sport+edition is a link to the post here. That is not available in the US. It may be they are doing the "is" editions of vehicles as US only so we get something special too.
I wish this had been announced a little earlier though. Gonna be a couple of years before I am ready to look at what is around then. Hoping it may be a new M135i or whatever they call it in Estoril Blue.
