I'm one of the few that I absolutely love the front end on the R. Just think there is something about it that is stunning in it's subtlety. Also, I think the Pret's are amazing.
As for driving, the reviews are raving about them, as are the people that own them. The AMG A45 and M135i owners have all gone very quiet about it.
Of course, I am biased as I get my R in the next few days.
