What was the worst car you've owned?

Mine would have to be a 1990 Mercury Sable Wagon that I bought off the front lawn of a frat house when I was 18 for $100. It had about 190k miles on it and it's brakes blew when parking in my driveway one evening thanks to the fact that the whole car was just rotting away. It couldn't go over 43mph without fluttering to pieces and if you closed the tailgate too harshly the fuel cut off switch would activate rendering the car stuck. It was good on gas, though. But, when you can barely go above 40 you don't consume much anyway.
