I am lately contemplating a move to a smaller car... it's a toss between Z4 and Mini (even though both are small, economics are very favourable for Cooper S while Z4 is just sex)... But those are about as small kind of cars as I'd want to willingly move into. The tiny isetta stuff - not when i have choice. The new Prius 2 looks great though and that's gotta be about 100mpg.
