I wouldn't touch the Electric Smart. It has terrible fit and finish, and the range is terrible for a fully electric cars (up to 58 miles), some plug in hybrids get almost as much fully electric range (Chevrolet Volt up to 53 miles).

Granted the Electric Smart is "only" $23K, but you have to look at the overall value (e.g. depreciation, utility, battery aging). I'd prefer to pay $27K for a plug-in Prius Prime (up to 25 mile electric, then gas).
