I disagree; for E90 and E91, I really dislike the front bumper and rear lights. If they make it along the lines of the E92, I'd be very happy. I'm sure I'm not the only one feeling that way. People buy the E90 because it's what's available, but if you see the surge in MB C class sales, you'd understand the need. My wife drives an E60, and that's a much better design.
According to wikipedia, Top Gear voted it as the ugliest car in 2005, and couldn't be bothered to put it on The Cool wall.
