You're forgetting the 911 owners who are now going to things like the VAG Action days.
Really, f*ck off home, you tw@ts - there are enough Porsche events to go to already.
Please don't beat about the bush and say what you mean!
As far starting on to trackdays, as everyone has said make sure your car is roadworthy, up to a days thrashing, remove all loose stuff and as much heavy stuff as you can be bothered to, and then go and have a good time. Most people at trackdays are friendly and always willing to lend a hand or advice.
Well worth doing a few sessions to get the feel and layout and then pay for a session with one of the instructors.
