220k is not super high for the gx470. If all fluids are fresh, then things that would worry me are:
1. Cooling system like radiator leaks, radiator hoses worn out, old cap, old thermostat, old water pump. If never replaced, it’s time to replace.
2. Bushings on suspension components might be shot like uppper and lower control arms both front and rear, sway bars, shocks.
3. Alternator might need replacing if never replaced.
4. CV boots might be leaking if never replaced.
5. Rear air bags might be close to end of road if never replaced.
If these items are taken care of, then 200k more might be possible.
Just my opinion!
