Not really sure how I feel about the M-Sport bumper. Looks like the car is crying.
These squiggly fog lights and mesh grille are just overstyled too. Not sure what trim this is.
I think less people would be complaining about the rear if they made the clear section of the taillights thinner. It would make the red L section more pronounced and have more BMW identity.
That being said, this looks like a great base/foundation for the M3. And from what we've heard, I can't wait to see what the next 4er looks like. And finally, kudos to the people doing the renders. They got the final look of multiple trim levels like 95% accurate.
