My 2004 Galant ES (2.4) has just passed 165K. Obviously with this kind of mileage you can see I am a commuter and need to keep my car running reliably. At this point in my cars' life I have performed little maintence other than the following:

Regular motor oil changes, transmission flush/fills, cooling sytem flush/fills, brake linings, spark plugs, tires, timing belt, water pump, drive belt and air filters.

I plan to schedule a fuel induction system cleaning in the near future. The car has been very reliable and currently runs well. However, I am concerned over the lack of direction I get from Mitsubishi Service Centers as well as the owners manual once you reach 160K. It seems either no maintenance is required beyond this point or your car is expected to die. Neither of which I am comfortable with. I recently visited my dealer and priced some various parts; ignition coils, wires set, spark plugs, wheel bearings etc. The only parts of the ignition system I have ever changed are the spark plugs. The dealer parts guy basically gave me the impression that I did not need to be buying coils wires or wheel bearings yet and I can expect significantly more life out of the original parts. I am having a tough time believeing this.

Does anyone have advice for someone who wants to keep this car running reliably well into the 200K mileage range? Are there any problematic systems in the 2004 line that I should be aware of at this stage of my cars life? What would you suggest for a tune up that goes a bit deeper than just spark plug replacement and cleaning/greasing electrical connections? Or is the dealer advice correct and my concerns are premature? Any information would be appreciated.
