If you made it that far on the original version of every single one of those parts, kudos. Doesn't sound so crazy when you consider that it's a Porsche. They're not exactly built like a commuter car meant to run forever before needing everything replaced.
Consider us fortunate -- the Mitsubishi Lancer Evolution IX has to have virtually every fluid in it changed at just 15,000 miles (per the maintenance schedule)...of course that's also a car like ours that's not built to just be daily driven for 100,000 miles and needing close to nothing.
Seeing as it can take some people 20 years to reach that mileage in a Porsche, it makes even more sense.
