I still don't think there's a savings for an electric car vs gas powered. Teslas are way cool and a luxury brand (see Hummer), so the electric part is just part of the novelty for sure. But I live in the Philly area, there are good number of Teslas around. But not really that many other electric rides as of yet.
My Jeeps stink on mpg, but I enjoy driving them all year. I always feel bad for those that always have to justify whatever they're driving. Like 'yeah its a -whatever car-, but it was a good deal and gets good mileage'.
