How do you pre-order a Z4

We all know the car is coming out in October. I'm going to need a new car then - but am loathe to pay the premium dealers exact on new models. Is there a way to order the car direct from the factory now - or are their ethical dealers out there who won't jack the price up 10k for the pleasure of my buying the car?

I understand its to be offerred at 32k starting.
