I hate to sound like I'm skirting the issue, but throughout automotive history, most French cars are a little weird and odd in style, but few are ever ugly. The latest Peugeots just suffer from having their individual part numbers corporate-raided and ruthlessly mimeographed after the theft, but they aren't really ugly.
The Citroen Ami, of course, is the exception...but it's a really ugly extreme of the entire automotive spectrum. One could say that a lot of Japanese cars are getting ugly now, whereby they excelled once at the simple and refined, and Ferraris are even kind of losing their lusty-looking ways in some cases.
It's funny to me that most recent American cars don't get the chance to be ugly; in many cases, there's been few styling risks taken in the first place. I mean, it's generally either retro, staid, or rather anonymously boxy with a logo-face. That's why stuff like the style of the 2nd-generation Ford Taurus is so polarizing: It's so many things to so many people ranging from weird to neat to ahead of it's time to Very Ugly (other than being a maintenance and repair problem-child). Style is a totally subjective thing, and our opinions are generally formed by what we've experienced in the past...something had to mold it in the first place.
