Worst car you ever owned? I'll start with mine I bought a 1999 Oldsmobile Alero from a place called Gustin's Automotive in Lexington, Oklahoma one time, this clunker broke down a few days after buying it, got it fixed then a week later it broke down again, there after every week to two weeks it was in the shop, final straw was when I was heading to the hospital to take my grandma some find a word puzzles & the head blew, after pushing it home I decided to junk it, I never had a car that required so many high dollar fixes back to back, what is the worst car you have ever owned.
