125k on mine. I have changed the separator and valve cover gaskets twice, expansion tank when it cracked, and thermostat and water pump as a precaution at 75k.

I had a freak situation where I replaced the engine wiring harness, but I hear this is more associated with gen 1 than subsequent years.

My driver's side window regulator is slow but all function. My suspension is all original so that all needs to go. My front halfshafts finally blew their boots and need to be replaced, but if you check those often you just have to do the boots and not the whole halfshaft.

A higher mileage X5 is going to need suspension, unless you are sure it has been done. It's not a matter of bushings; the entire members get the heave ho.
