The 15K oil change (paid for by BMW of course) is bogus. They should be doing it every 7500 or less but the free maintenance will not pay for it...

This is great advice. I bought my 330ci new and according to the dealer the car did not need a first service (including oil change) until 25,000 km!! WTF? Everything I have ever learned - about new cars in particular - is that it is prudent do some fairly frequent oil changes in the first 20,000 km. BMW told me this is no longer necessary due to new synthetic oils etc.
Fortunately I know a good BMW mechanic - who tells me the BMW party line on oil service intervals is crap - and that I ought to do oil changes more frequently.
So far my only disappointment with this car has been that B.S. that BMW tells you about oil change intervals - thereby seriously compromising the integrity of the cars they sell.
