If you are looking to pay MSRP or a little less I would suggest looking into ordering your car through a broker such as
www.cartelligent.com That is where I got mine from, that is also where my Dad ordered his M3 from, we both paid slightly less then MSRP due to the process that a broker acquires a car from a dealer, the dealer saves money by dealing with a broker becuase he does not have to pay a saleman a comission on the car.
