To my eye, the Fit is a jangle of weird and incongruous lines and angles. Visual dissonance. The design is so busy my eyes get tired just looking at it.
Second, I propose the new Hyundai Elantra.
Just freaky. The swell over the rear wheels clashes with the horizontal line running along the main part of the body. I understand this is part of the new Hyundai design language (and I hate that term, but all the auto magazines have glommed on to it), but it is carried off much more smoothly in the Sonata. The Elantra's tail lights are garish and look like part of a Halloween costume.
If you are offended by my suggestions because you own one of these cars, bear in mind that I drive a 2010 Toyota Corolla, which certainly is not going to win any beauty contests.
