The "S" is good on speed if you like to go in a straight line or pass a slower car on the highway one second faster. The standard Boxster 2.5 or 2.7L will keep up with an "S," and most 911's, on any mountain road or twisty highway. My '99 986 is a Tip and I took it to Sears Point to open night drags once and lost in the semi finals by less than a second so they're not exactly snails. I've owned my base Tip for 6 years and haven't wanted any more power except up the hill to turn 7 at Laguna Seca and everyone wants more power there.
