Hi! My wife has essentially expropriated my brand new 2006 530i for herself

, so I'm thinking of leasing a 2006 330i soon. I'm told that there exists "confidential" "best" lease rate information from BMWNA that's available? If so, does anyone have this information?
Alternatively, I'm considering a 2-year lease (either 12,000 or 15,000 miles/year is fine with me) --- what would be the best Money Factor and highest Residual Value available from September 2005? What should I negotiate towards, basically? Also, I understand the relationship between Cap Cost (price of car), Money Factor (interest rate), and Residual Value (self-explanatory), but are there other sorts of "fees" or "charges" that are normally added on and which I should look out for? Finally, do dealers do leases for ED purchases?
I'm actually entirely new to leasing so I'd appreciate as much help as you can offer me. Thank you all so much in advance for your kind help!
Cheers!
