See the above link for SOME of the costs of hybrid cars.
They actually cost far more than they save. For a truly eco-friendly vehicle, anything that gets high gas mileage, be it diesel or gas, is better. I'm waiting on the diesels until they figure out engine longevity with the new low sulfur fuels. I'd love to see a TDI diesel in the states, but I don't think it's going to happen until the EPA stops cutting off our noses to spite our collective faces.
