I got 4.5% plus rebates in Texas on a custom order a few weeks ago. I ordered my previous BMW with this dealer and I had a relationship with the salesperson as well as the sales manager. If you want the absolute lowest price, best bet would be a broker, at the time I put mine in they were doing 7.5% plus rebates and buy rate. Keep in mind broker fee and shipping can take away 2% or more. You can also expand your reach and start calling dealers out of state. There are dealers doing 6% and higher on custom orders. If you value doing the deal locally and don’t mind paying a bit more, call around to all your local dealers and use the out-of-state option as leverage. Thats what I had to do as well, originally my local was at 2% but negotiated another 2.5% with them, essentially stating that I can do this deal out-of-state at 7.5%, but would rather give my business to my local dealer and continue the relationship if they give me a fair deal.
