There could be more complex things going on with pricing but I don't think BMW offers many manufacturer to dealer discounts for M3s.
Dealers may be more motivated to sell cars on their lots as everyday they are making interest payment on those cars. However a newly ordered car costs them nothing.
Also if M3's are a hot item in your area, maybe you have to pay full price. Hope not.
I got 8% off of MSRP (including options) on a non cash deal in Aug'11. Total discount came out to approx. $6,800.
