Everytime I'm asked the "Mileage" question and respond with an average of 35MPG, folks seem unimpressed (yes, even my wife).
I never miss an opportunity to let these folks know that the SMART story is not all about MPG. If you look at the carbon footprint over the lifecycle (Production, Use, Disposition) you'll find that the car is built in a state of the art green building, produces the lowest carbon footprint during use and is 95% recyclable.
Karl is correct that the the reports on carbon footprint only account for the use part of the product and do not account for the disposition of the batteries of the hybrid products.
Overall SMART is a VERY smart choice for being "green".
