A service history from the previous owner(s) would be helpful in knowing what's been properly maintained vs neglected. In absence of history at 99K I would definitely do engine oil+filter, air filter, brake fluide, coolant, power steering, transfer case fluid, differentials fluid, fuel filter, transmission fluid+filter, and spark plugs at this milestone.

Check drive belts for cracks/wear. Inspect coolant system components for small leaks (white/blue powder from dried antifreeze). Replace expansion tank before it cracks - because it more often does after 100K at the most inopportune time. Check coolant hoses for wear.

Parts don't last forever, especially on BMWs. Good luck.
Great points skeet. As for the history records, that's what I'm trying to do is locate prev owner which I have a thread on. My local dealer tells me if I know where the car was serviced, i can call that dealer and they can pull records but unfortunately I don't. Probably some dealer in CA!

What is the function of the expansion tank? Where is it? And is it easy to replace as a DIY ? I'm pretty handy and mechanically inclined?
