 My first BMW was a 1987 325e and it ran perfect for 280,000 miles other than normal maintenance.At 280k the coil burned out, I put a new one in and 2 weeks later and the same thing happened.I tried one more time and the same problem so I sold it DOA.I bought a 2004 BMW 330Xi with 59,000 miles on it.My car now has 99,000 miles on it and here are all of the items I replaced.Complete CCV cold weather kit, Crankcase Vent Valve, Oil Separator Hose, Breather Hose.Valve cover gasket, valve cover, power steering pump, spark plugs and coil pack, rear springs, cv joints, DISA, multiple alignments because of pulling, brakes, and now it has mustard color under the oil cap.Updated 4/1/2016.I finally traded the car in to dump this lemon.  It ended up having a bad head gasket.  The car was never overheated and the antifreeze was rated for well below temperatures we have in Wisconsin.  During the winter it would suck down the antifreeze.  Not worth all the trouble and I will have a hard time considering a BMW in the future.  I replaced it with a Honda Pilot and the Honda now has a 125k trouble free miles on it.
