dunno - I don't think there is a typical because it totally depends on the use. Were those 80K miles on a race track? off road coarse? Pot-hole infested inner city? heavy mix of snow driving in the winter? smooth interstate in sunny CA?

My X5 had a lot of highway miles and I purchased it with 95K on it already. According to the BMW dealer that did the PPI, the only item that was wearing out in the suspension was the thrust bearing, or something to that effect. I figure I will replace that soon but have not gotten around to it. But the vehicle drives and rides really nice, so I don't think it really needs shocks just yet. Maybe in a year, for sure in 2.
