Thats a question that I should realy need to answer, but here goes anyway
Its the same reason why someone would want chequers put on their mini roof, but i wanted something different to what you can get in the bmw options list. You could say its just a large bummper sticker, its there because I like it and want it there not because some joe boy bloggs thinks that it looks stupid. Its also the same as buying alloy wheels instead of having steel rims, as the majority of people get them for the look rather than, if the wheel is lighter or wider.
