That Ferrari 288 GTO rocks. I see where people might think it's ugly, but jeez. It's a Ferrari!
I think the 1984 Mustang SVO is awesome. The front end is, well, a bit weird. It was more of a transition from the 1983 front end to the 1987 front end (flush headlights and a parking lamp on either side of the head light). But, of the SVO's, I think the 86 is the ugliest because the lights and parking lamps were flush, but it still did not look right.

Nevertheless, the SVO was awesome. 2.3L Turbo 4, 190 HP, big fat tires, and lots of fun. My buddy from highschool had an 84. We had a blast in that car.
