Right, at least the Smart CDI gets 70-80mpg. But Noooooooooo, diesel is EVIL in the United States Of America! We can't allow a car that gets 50% better economy and lasts twice as long, it might raise the atmosphere's temperature by 0.000000000000000001*F!

I agree, if it got 100mpg it would be something worth considering. But since it gets less fuel economy than cars that are bigger, safer and more powerful it isn't more than a "green" status symbol. No better than a Hybrid.
