CMV: If your goal is to limit your carbon footprint you should be buying old used cars and not new "eco-friendly" ones.

Buying hybrids because they're better for the environment really seems like a disingenuous action to me. If your main goal is to reduce your carbon footprint, then why are you supporting the manufacture of new products when used ones are still available?

The civics/geos/sprinters/metros of the 90s and early 2000s rival current hybrids with mpgs in the 40s. 

A large portion of emissions generated through a vehicles lifetime come from the initial manufacture and transport too, so why wouldn't you just buy something that already exists and drive it till the wheels fall off?

Purchasing new hybrid and electric cars promotes the development of new eco-friendly technology. The people who bought the Tesla Roadster gave Tesla the capital to build the Model S. The people who bought the Model S gave Tesla the capital to build the Model 3. This support fuels innovation for the future.
