Routine Preventative Maintenance

[jdvl2010]

I just recently purchased a 02 Boxster with 27k miles in excellent condition. I am hoping to keep it in good condition for a long life. I am curious what kind of preventative maintenance I should watch out for and any known issues with the car. I am aware of the IMS issue and do watch that when I change my oil. Also what are standard times to bring the car in for checks with the dealer.

Any information would be great! I've already very much enjoyed reading through post on here for numerous amounts of information regarding my car.
