We have been lucky. Replaced accessory/drive belts and battery at 60K. Everything has been just routine maintenance items like fluids, filters and tightening a few bolts.

On the 2004, you can replace the oil filter while sitting on your lawn chair, but have to wait for the engine to cool off a bit.
