I enjoy that BMW has played opposites since the E65.
Basically, extrememly agressive sedans and very "sleepy," subdued coupes and roadsters.

I was never a huge fan of the 6er's headlights, but it all made sense with the original 645i's wheels, because the porportions and lines told the same story.

With these 5-spoke wheels there's soo much negative space, which compromises the rest of the car's lines.
