Dont like the exaggerated kick up on the window at the D pillar, kind of pointless, why not just keep it flat and follow the tailight curve up?
BMW originally put the "Hofmeister Kink" on the 1500 back in the early 1960s (so named for the head of BMW design at the time). The kink, along with 4 round headlights, the kidney grill and a swedge line running the length of the vehicle, are the 4 cornerstone styling cues that make a BMW well, a BMW.
In fact, the only BMW not to have the Hofmeister kink (excluding convertibles of course) was the original BMW M Coupe. The Kink visually helps set the chassis on a forward and more aggressive stance.
Not to be disparaging, but the Japanese quickly copied the Homeister kink (Lexus being the number one imitator of this design cue). Unfortunately, they generally miss the point of it and make it way too big. Where the BMW version is very subtle, the Japanese tend to make it into something huge...
