What is the worst car you have ever driven and/or ridden in. When I say worst, I mean to drive not to live with. The worst car I have driven was the 2005 chevy Malibu MAXX LT v6 loaner car from the dealership. It needed more power, it swayed like a boat, and the seats sucked. The worst I have ridden in was a PT cruiser. There were squeaks everywhere!
