What was the Worst car you've ever owned?

I had a 2006 Ford Taurus that would've been stronger if it was built with Legos. Water pump fell off one day - like... just... fell off. The brackets weren't broken or misshapen or anything like that, it just fell. None of the bolts were loose or unthreaded or anything. I know that doesn't make sense. I KNOW. It makes even less sense that it happened twice.

There was also some kind of electrical issue that I could never isolate, but it was causing fuses to blow out every couple months, and would burn out the starter about once a year. I had to replace that starter so many times that I stopped needing to refer to my Chilton book for the steps. Sometimes the power steering would just stop working and then start working again with no warning.
