A LOT has changed, that's what. Toyota went back to basics for the third MR2, gave the car a hair-cut, lopped some weight off it and gave it a squarer look and stance. The result may not be as pretty inside or out, but it seems to be effective in its primary role - thrills for the fan of open-top motoring on a budget. Not everything works of course. The gearshift is gimmickky and the looks - from the front in particular - are derivative.
