What's the WORST car/truck you've owned?

The worst 40 days of my life was in 1977 while owning a 71 TR6. Underhood wiring burnt up because some idiot disconnected a piece of emission eouipment and left it to short out, smoke would roll up through the floorboards from the overdrive and the coup d'gras was dropping a half shaft in downdown Seattle during rush hour.
Told the tow truck driver to deliver it back to the dealer and called the dealer to tell them where to park it.
