That hasn't proven to be true as my car has gone as high as 6500 RPM (in an accidental 1/2-second moment of downshifting too quickly at a high speed).

Was he referring to a limited SUSTAINED RPM of 5500 or what? I certainly don't want to mess with it, but I'd like to know the facts on this.

On top of that, my M3 continues to alert me that I need service even though I'm only half-way there. My dealer says to ignore it as 1,200 miles is the golden number. Okay... so I ignore the alerts
As others have noted your dealer is wrong, probably about many other things as well.

The only pre-1,200 mile thing I "might" have noticed was that the shift lights seemed to start coming on at something like 5,500 rpm whereas they now don't start popping until 7,000 or so. I don't think it was my imagination but then again...

I was the only one who drove it respectfully, even though everybody else was abusing the crap out of it. I personally don't believe anything bad will happen if you don't stick 100% to the break-in recommendations, like an ocassional run to pass a semi or something, but NEVER redline a brand new engine incessantly. And yes, that's why I never buy a demo car .
Yep "DEMO"S" get thrashed, I would not buy one either.
I thrash all the demo cars I take out.
Live for now, life is too short.

How is it that evinrude can make an engine that doesn't need a break-in, but BMW cant?

Ah, but my Mercruiser had very specific guidance for break-in during the initial 20 hours, with a service at that point!
