Sorry, obtuse doesn't work for me. I have to deal with too much of that at work. Besides, even though I'm a car buff, a Yugo is so far off my radar, that I don't really care to know what they look like, let alone be able to identify one on sight. The only things that looks uglier to me that that are those new Scion boxes, and the Honda Element. Soviet styling at it's finest.
Well, I'd prefer the term obscure. But I get your point.
