just did 100k in August - radiator flush, fuel filter, brake service, tranny service, differentials, spark plugs (which showed burnt oil, which lead to...), valve gaskets & valve cover gaskets - also replaced the coolant hoses behind the 4.4 engine - all done at my Idaho Falls BMW dealer, whose rates are equal to my indy repair in Charleston, SC - meaning they are much lower than "normal" BMW prices - my indy also recommended replacing the timing cover gasket.
