The all time ugliest car has to be the AMC Pacer. Vegas were junk unless it had the V-8 Conver done. There were a few really fast ones around Akron in the late 70's. One even had a 454 in it and a 9 inch rear. If I remember correctly it was either HotRod or CarCraft did an artical on a wind tunnel test of a Pinto drag car and it was faster going backwards.
