At 200k miles.....
Like previous members have stated check the:
1) control arm bushings
2) rear sub-frame mounts/bushings
3) Essentially, go to your mechanic and say, "Check all suspension/steering components [i.e. trailing arm bushings, ball joints, etc.]
4) water pump [better do it now rather than later. Do this along with coolant.
5) checking transmission/differential, power steering fluid
6) I don't think it is really necessary to do brake and coolant if you are following the prescribed 2,3 year plan, respectively for flushing them.
7) Ground wire for battery.
There is a slew of other things to check at 200k miles. However, as previously stated it really depends on how the car has been taken care of and how thorough you wish to be? If it were me I would pretty much check everything / do everything just so that I could have a fresh clean slate when I break the 200k barrier and insure another happy 40k miles. Furthermore, at 200k you are coming up on Inspection II.
All hinges should be greased. Window guide rails should be re-greased. Check your A/C system as well.
Anyways....
