This is my "custom" body work which consists of a euro front bumper, the later US front valence, and $5 autozone turn signals. At first I thought it looked a little funny but it has grown on me and now I can barely stand to look at e28s with the stock super bumper.

I made a pair of mounts like this for the bumper (the BMW mounts and associated doodads really add up if you buy new, and require modification of the frame rails).
