Does anyone know how the tracking system works for a X5? This is how my car progressed

On the owner's circle website status changed like this

On Order > Scheduled for Production > At preparation center! It skipped 2 stages in the middle. It has stayed in "At Preparation Center" state for nearly 7 or 8 days now

Through the 1-800 number
The status was lot more granular, but the final stages my car has been going through is making me wonder if the phone system is correct at all

* In paint shop
* Waiting for release to carrier
* Released to carrier waiting for transport to port of exit - 05/08
* In transit contact BMW center - 05/09

When the car went into Released to carrier state on the phone system I talked to BMW Customer support and they told me that my car completed production and left the SC factory on 05/04. Now only my dealer can give me the status.

My CA expected the car to be at the center on Friday 05/11 (today) but my X5 is not here yet. Now he says it should be here by monday. Does anyone know how the telephone tracking system works? I just can't stand the wait...
