A Saab is way too fun to drive to be boring. Find a twisty road, and try one!
I have to go for the Koreans Hyundai and Kia.
I think the worst current car is The Kia Carnival.
It has horrible performance, even for an asian van, and it is no fun to drive. Another problem is that it only scored two stars (of five possible) in the Euro NCAP crash test. It's less safe than any small car on the market, I think.
