I've been to the San Diego Porsche Performance Driving School and it was a blast.
You don't need any experience at all other than knowing how to operate your car (ie shift, steer, brake, turn traction control off etc).
You will be spinning out and breaking heavily so your brakes and tires have to be in decent shape. You will be wearing a helmet so either get your own or use the rentals. You can pick one up for under $150 or borrow one that "current"(ie 2010+).
Try saferacer.com amoungst many others.
You will also be bumping cones so if you are afraid of minor scratches you can blue tape around the edges of the wheel wheels, and front bumper.
You will learn how to drive YOUR car like a racer, to the limits of its traction and your ability with an instructor in the passenger seat.
They group the students by car type so you will learn all the tricks and quirks of driving your Type. (mid engine, rear engine, front engine)
There is a classroom talk that teaches the concepts of the racing line, apex's etc and is very enlightening.
You will also learn collision avoidance maneuvers, some of which are counter intuitive but work incredibly well.
Many exercises are done on wet soaped course so you will learn great wet handling skills as well.
Its so much fun many folks do the course more than once.
I doubt anyone leaves without a big grin on their face and becomes a much safer driver having learned their car's and their own limits.
(Blue student shirts say ... "Sometime in order to find your limits, you need to exceed them" ....exactly what happens during the course )
Also, you'll make some new Porsche friends and its a perfect intro to Auto-x and DE driving.
All smiles as far as I can tell.
