The Boxster,and its even more-potent sibling the Boxster S,offer a full dose of legendary Porsche performance at prices that don't require the buyer to be a star athlete or movie celebrity. Porsche did not skimp to keep the price in the somewhat-affordable range,equipping both cars with sophisticated suspensions,state-of-the-art transmissions and a choice of two potent mid-ship-mounted ""boxer"" six-cylinder engines. For some,the alluring lines and Porsche nameplate will be every bit as enticing as the performance aspect,offering up the kind of head-turning quotient you won't experience behind the wheel of a Mazda Miata or Chrysler Sebring.
