This is what i plan to do on my 120K miles 997. All of it applies to you.

Water pump and thermostat (Get the Porsche ones)
Accessory belt, all three pulleys
AOS
Coolant tank
Heat exchanger seals
Battery, and + cable
Starter and Alternator rebuild
Spark plugs, and ignition coils
Oil, air, fuel filters
Brake rotors and pads for the front
Front tires
Shock mounts for the rears
Heater box in the front.
All fluids including the tiptronic.

All those are running me $4,000 in parts. Labor is free (to me).

In your case, you want to add O2 sensors to that list. For the suspension bushings, those are ... as needed, as wanted, as cash allows.

Deferred maintenance catches up, and then you pay through the nose. You drive a Porsche, you just ... pay.
