Real MPG: Smart Forfour (2004 - 2006)
Funky-looking, versatile hatch with plenty of safety kit. Manual versions drive well. Four stars for the diesels, by far the best in the line-up.
Slow gearshifts with the semi-auto. Not all second-hand ones will have a three-point seatbelt for the middle rear seat. Could have been a contender but arrived two years too late.
