You folks have a warped sense of reality.
Reality is, people who track their BMWs are probably less than 1/10th of 1% of the population. For any BMW center to accommodate the likes of "us" above and beyond servicing their normal customers would make zero business sense. For service advisors to be TRAINED to manage the expectations of those of us who track? Makes ZERO business sense.
That said. I had a service advisor who used to track his E39. We had a great working relationship. When he left the dealership I was very disappointed. His replacement knew nothing of what these cars can really do in track, and some of the stuff he used to go above and beyond with for me, like flushing my brake fluid with what I bring in when I ask, without a question, were met with far more resistance than necessary.
But hey. Such is life. I got lucky with a service advisor. That luck was not to be repeated again since I've learned to do the vast majority of the maintenance work myself, and have found a trusty Indy mechanic to take care of what I can't.
The hell I don't! LISTEN, KID! I've been hearing that crap ever since I was at UCLA. I'm out there busting my buns every night! Tell your old man to drag Walton and Lanier up and down the court for 48 minutes!
