oh - will add I've had my X5 for a year plus a quarter and logged 16K miles including the 4K to get it from KY to CA. So far all I have replaced is an AC fuse and a CV boot, for which I ended up just replacing the axle after stripping the threads on the original spindle. I think that cost me about $75. Oh - I guess I did a bunch of maint - replaced all the fluids, spark plugs, air filter, cabin filter, fuel filter, etc. So that was a couple hundred. And I did buy the hardware to replace front brakes which was about $400, but all cars use up brakes and tires and need periodic maint, so I hardly count those costs since they are relatively constant from car to car within certain classes and sizes of vehicles anyway. And of course if all of that had been done by a service dept instead of by me, the costs could have easily been well up into the $1K's, since I hear dealers charge upwards of $2K just to replace the brakes on a 4.6is.

Only things that went wrong on mine prior to 100K miles was water pump, coolant expansion tank, alternator and oil leaks from valve covers and the pan. All fixed under CPO. So much of the common failure items have been addressed. I need to watch for the valley pan failure - so far that hasn't happened. And I really should replace the radiator even tho the dealer checked it out 15K miles ago and all was good. Over 100K you are rolling the dice to some degree - although at least the expansion tank and some of the hoses were already replaced.

Anyway - all pretty common stuff from BMW's of this vintage.
