Glad to see quite a few X5 with that kinda mileage.

Just replace the WP on my 4.4i with 58k (well the upper hose radiator crack so I decide to overhaul the coolant system minus the radiator). FYI, the old WP with composite looks good, no play in the bearings, and turn smooth. Also the old thermostat looks clean, no rust, no gunk in it.

Hope it'll make it to 100k and beyond, just got back from Seattle autoshow no cars I like is under $60k so have to keep this one going for a few more years.
