My 2 cents
I voted for the bumper as I think I basically believe the Car Magazine "scoop". I would prefer the trunk but could definitely get used to the bumper if it looked more like the M6 rather than the p-chops in the mag. But darn, then again, could it be that only Euro sized plates actually clear the flow from the diffuser on the M6?? BMW couldn't have been that EU centric ignoring their largest market could they?...
