Hi guys... im from GCF's,..but became rather intrigued at this "3er" spy pic.
After some long hard stares at little aspects of this bodyshell... i spotted a few differences, aside from the obvious differing lights.
I marked out a few of my observations..
A) Unlike the E90 3er which has a more smoother side merging with the bootlid... this bodyshell seems to have a more obtrusive style, ... which IMO signifies a more aggressive design.... ie: trying to look more "beefy".
B) While the new 3er's crease runs from the front wheel arch all the way to the rear light, this shell's crease ends just after the fuel-tank hatch.
C) If u compare the rear bumper split of the E90 3er, u will see that the 3er's line continues at the same angle as the shape of the rear light and then curves towards the rear wheel. Looking at the spy pic of this body shell, there is no curve, just a straight line from the bottom-right of the light compartment to the wheel arch.
My guess is as good as anyone's here..... so im guessing it might be the M3,..but that's just a long shot.
