The worst looking back end, in my humble opinion, was that of the late 70's GM "N" bodies, Olds Starfire, Buick Sky Hawk, Chevy Monza. It looked like the designers got to the back of the car and said to themselves, "OK, now what?"

I owned one and can tell you it got a lot of angry smirks from all the street racers who had to look at it. Same thing with either of my Crossfires. But the SRT must be the ugliest, from the number of p!ssed off views I see in it's rear view mirror.

BTW, My wife drives the SRT home at nite and i follow in the NA roadster. I have to tell you, I'm looking at her rear end and liking it all the way home.
