you peaked too soon man. Its all downhill from here as far as sports cars.
Unless you buy a Ferrari or something. I'd love to see your car insurance bill.

You should start autocrossing. At your age you need to learn the limits of your car in a safe enviorment. That way your still developing that frontal lobe of your brain (ins't fully mature until age 25'ish). Having a full sports car envio understanding of your boxster won't tempt you into NOT going for the brake in a dicey situation.
Younger people are for some reason numb to the survival instinct of impending disaster. Its not always an issue of bad judgment (street racing) its the mind's ability to sense danger before its 10 feet away.
I have a friend who learned how to drive a car PERIOD on an autocross course.
That's the way to do it!
