Those Ssangyongs would get my vote for ugliest new car, but they're not sold in America. What's with that redundant first "S", anyhow?
The PT Cruiser Convertible just looks horribly proportioned with the top up, and looks like a mutated basket with the top down. This is a car that was a hit when it debuted as concept car, and it's both original-looking and practical with four doors. It shouldn't have been messed with to make a convertible; it looks like it was designed at the last minute.
