I got my 335 from Hahn X over invoice and my M3 from Bellevue X over invoice as well.
Alvin at BMW Bellevue is a very straight shooter. Once him and I agreed on the dealer profit, he just gave me the order sheet and I built my car. Overall, very good experience.
No one is going to get my business by doing me a favor of ordering a car $500 below MSRP.
GL and keep us posted. Just don't get ripped off
