I think I'm one of the only people in the world who thinks the 4 series is ugly, fair enough the side profile is a lot neater than the old 3 series coupe, always looked a bit odd at the rear 3rd.
But front facing and the rear look like a curvey Korean explosion, like they don't know where to start curving, bending, linking. All just a bit messy, and those side grilles look so add on. i loved the bangle styling with all the concave and convex sheetmetal, and the constrasting light that was formed.
Probably get told I'm a retard now!
