Ignoring the obvious hofmeister kink, I see 3 major design queues they both share. Most notable, the major body crease along the side is nearly verbatim. Save that the Merc chose to put the door handle in a random location. The area right before the base of the A pillar, and the geometry around where the M3 side blinker is located. The window layout is also remarkable similar when the door is shut. Though I'll include this as a result of the kink being there.
The roofline in general is similar, but it is a coupe so that is definitely acceptable. Anyways, it's a good looking car. But considering at least how similar the body is to an e92 I don't really share everyone's sudden urge to shun the M3 and rush to the Merc dealership.
