faster, cheaper, smarter...you name it! Getting into a power war is not the way to go. Enjoy the car for what you have...a PORSCHE! He is driving a DODGE NEON! Your car is perceived as "mature, expensive, good taste, etc... His car, well...immature kid, lives w/ parents, still trying to build an identity. Next time just smile, wave, keep the mystique of "what if" in these peoples minds and you will drive away with a certain guaranteed satisfaction!
BTW-no offense to those Boxster owners still living at home!
