Since the F30 is relatively new, there currently is a trend within their community to install hybrid bumpers - which are made by combining sections of various BMW and aftermarket items.
I've seen pics of F30 with a hybrid 1M bumper fascia, etc. If I remember correctly maybe in one of the Bimmer issues?
Anyway, I'll keep an eye out for the joker.
