Why would PCA members look down on your 2002 S? It has more power and better handling than nearly all the air-cooled Carreras ever built, and those are by far the most coveted by the purist. Not bad for your first Porsche selection! But hey if you're lucky one day you'll get to own a slower Porsche that leaves you a new mystery fluid on your driveway each morning. Afterall sports cars aren't really about driving fast and water-tight engineering.
PCA members often receive like 10% discounts at their local Porsche dealer for service or parts. And Autocrossing with the local PCA chapter is the single best bang for the buck motorsports activity. Basically they'll provide you with the same basic performance driving instruciton for $50 of autocrossing that you'll get paying $2,000 at some driving school where most of the lessons won't fully sink in after just one day behind the wheel.
p.s.
I spend a lot of time down in Florida and I totally get where you're coming from with this question. Especially in South Florida, the price of your Porsche seems to be some sort of status symbol in many circles down there. It's not enough to just have a Porsche, you have to have the expensive GT3 or Turbo with the sunroof and premium edition Starbuck cup holder (LOL). But hey lucky for FL they will always have Sebring. The Porsche guys down there who actually drive their cars are nutters!
