Almost all 2 door autos designed off a 4 door car do not work well. BMW is no exception. Except for the e30-e36coupes, which I favor over their 4 door counterparts, I prefer the 4 door designs. The 2 doors just look stretched to create the 2 door version and the deminsions seem forced. The E92 is the worst of these.
With all that said I really like this new 4 series basic shape. When they pull off the bloated hood camo and rear mess it may be very appealing. I had wanted a new F30 M3 but this design has me considering the new F32. This seems to be a shrunken 6 series which has always been too bloated.
