If those filter changes don't include regular "fuel" filter replacement, you can count on replacing the very expensive fuel pump eventually. The dealer told me they recommend changing them every 15k miles.
You should start thinking about changing those engine "idler" pulleys too.
Look forward to the intake manifold to start leaking as well, but that's a ways off.
My 1999 Chevy 1 ton "extended" window van now has over 250k on it, but that is just some of the "maintenance" work it's needed.
For comparison, an old 93 Civic I had went over 250k with nothing more than a routine timing belt & water pump change at 110k, a torn CV joint "Boot" replacement, and a radiator replacement, because I never flushed the anti freeze in 170k.
I'm a firm believer that GM likes to keep it's service technicians busy.
