Not all of us considered the blue-and-yellow of Jerry Seinfeld's Porsche 911 to be quite so bad, though that put us in the minority. We're also totally smitten with the grey and red velour of the 1971 Fiat 130 Coupe, but that may not be a commonly held taste. The snakeskin green + black + red of the 2008 Viper SRT10 is both garish and ridiculous, which actually makes it perfectly appropriate for the Viper SRT10. There may be nothing more frightening than the purple-on-purple Porsche, an eggplant abortion that only a Spice Girl or a true Porsche fan could love. Amazingly, everything mentioned so far came that way from the factory. We haven't even mentioned custom paint jobs. You tell us, what's the worst-of-the-worst in car-color combinations?
