Entry-level Porsches always looked sportier than they drove. That is, until the BOXSTER cruised along. The $40,000 ragtop will set your pulse racing just as quickly as its big brother, the 911, does. Shift through the gears on a curvy country road, and there's no doubting the two-seater's race-bred heritage. And the interior, with swooping lines and neatly packaged controls, is light-years ahead of its clunky predecessors.
