My 03 automatic is coming up on the 100,000 mile mark, and I was wondering what maintenance I should be performing. I haven't had any enigine or drivetrain problems so far, but I want to be proactive.

Timing belt and serpentine belt, Plugs, trans fluid, fuel filter and airfilter. Check the back of the owners manual.
What about CPS and the thermostat. Wait until they go bad or replace now? Also, what about diff. fluid?
I would wiat till you had the symtoms before replacing parts, especially the t-stat, that's about an 8 hour job.
Timing belt and water pump is $600 - $800. The t-stat, sparkplugs and the CPS you may want to tackle yourself.
