I have driven a lot of piles of crap but it was more due to improper care/setup/maintenence than the car itself. Worst car that I have driven without any mechanical defects/alignment issues/etc. has to be a 1997 Nissan pickup. My dad bought it to have a truck around the house and I rocked it for about 3 months while my car was in the shop at the time. Completely gutless, rough ride, power nothing, and an incredibly cramped cab. I am only 5'10", pretty average, and with the seat all the way back I was still uncomfortably close to the steering wheel/pedals.
