Mines just a baby at 123k. Put the blower on around 100k, and put the cam in last weekend.

Replaced:
1 hub
shocks
steering box, inner/outer tie rods, pitman arm, idler arm, idler pivot
A/c compressor (not cheap )
Rebuilt trans (due to terrible tune by wait4me)
passenger front speaker
driver's seat memory module
backseat seatbelt tensioner

I know there's more but drawing a blank right now
