Dear Dorkiphus members let me clarify Porsche maintenances. There apparently is a lot of confusion over what the regular services are. And I have rarely seen the list itemized on a dealer invoice.
The Porsche maintenances are checklists for the most parts of items to look at on the car. This is the 30K checklist for the SC. As you can see oil change , valve adjust and plugs, filters and other small stuff is mandated for replacement. The labor for these items is included in the cost of performing the service. Valve adjustment takes a little time to do. This is probably 30% to 40% of the time for the whole basic service. (by the way what happens if a head stud rolls out of the cover?)
The rest of the items in the checklist are open. What happens if you need calipers and rotors? Is that a part of the service? No. It is extra. On a 22 year old car what is the probability of going through this checklist with no problems? What if it needs an alternator? What if the CV's are gone? You are all familiar with the common failure points to a 911. There is no way, especially on an old car, to predict what it is going to need unless you are the person who has been doing the maintenances for a period of time. (Much the same way when you visit the family doctor for years. He has a history of you.)
As a result there is no way you can predict an exact figure for a maintenance on an old car you have never seen before.
