M3 Servicing and Inspection 2 costs

Hi all,



What is the average cost that you all pay for the following and what is necessary? I have looked at a number of M3s, but a lot of M3s have only ever had their oil changed every 2 years or 15-20000kms (as specified by the Odometer). Would this deter you from buying an M3? Is the TWS a Long life oil?



Personally, I have always changed oil every 5000kms or 6 months.



I assume this is what is involved



Oil Service:

10W60 TWS Oil

Oil filter



Inspection I: (average cost?)

Oil+filter

What else is involved?





Inspection II: (average cost?)

Oil + filter

Air filter

Spark plugs

gaskets?

belts?



Valve adjustment ($?)



Rear subframe reinforcement ($2.5K+?)



SMG pump replacement ($?)



Vanos ($?)



When should things like the SMG fluid, power steering fluid, diff fluid and tranny fluid be changed? Is this done in an inspection 2? What about the fuel filter?
