Good words of reason (what? we're trying to reason with each other?:angel
Three points I'd like to make: On my E46 330xi, I replaced most of the cooling system at 100K. Didn't replace the pump, which was still good at 145K (water pump failures don't immediately toast the engine if you're half alive and watching the gauges). YMMV, but there's the other side of the bell curve, too.
I replaced all the tranny and diff fluids on Mike's schedule. My front diff broke. And I got rid of the car because the center diff was in the process of failing.
I changed oil at 5K-7.5K intervals, and the thing used a quart of oil in 1200-1500 miles at tradein. CVV worked perfectly. Still perfect compression, engine valvetrain was spotless.
Face it; parts are gonna break and many times insane maintenance regimes don't matter.
Having owned vintage ('77 530i and 320i) BMWs that needed more maintenance, I can assure you that todays are much more reliable, even if you just went with BMW's reccos.
