For Porsche owners, can you give me an idea what kind of maintenace you would need to do other than oil changes? I know it costs about $500 per oil change but you only do once every 10K+ miles or so, which is about the same for the Z if you do it every 3K miles at $99 each.

what other maintenance would be required? how much?
