Rear Comparison: Z4 M Sport vs the Z4 35is

Many critics say that the Z4 35is does not have a nice rear. But if we look at a comparison between Z4 35is and the Z4 M Sport, there is obviously a very small difference. If you look at the pictures below, they virtually have the same concept, aside from the fact that the color of Z4 35is’ rear faux defuser is painted with the body color, instead of standard black that the Z4 M Sport has. This difference lessens the Z4 35is’ sporty apperance, but still is a beauty in its own right. What do you guys think?
