Start talking about your favorite car or truck and chances are you will be get a visceral reaction out of many Americans. Where I grew up in the Midwest, for example, saying that Toyota made a better truck than, say, Ford or GM...well, them'z was fightin' words to some. In other parts of the country, the same might be said for debates such as, "Which sports car is the fastest of all time?" We do love our cars.

But, then, there are those "ugly ducklings" that should never have made it off the assembly line, and which, sadly, never blossomed into swans. This week, Businessweek assembles a slide show of the 50, all-time ugliest ducklings on four wheels...If you are passionate about autos, or just want a few laughs before heading off to nighty-nighty land, then check out this slide show. Yeesh!

Those are REALLY ugly....LOL
