I just leased 335i M-sport but i think the deals are all pretty much the same. Money factor and cash up front will depend on your credit rating.
Aim for the following:
Money factor: Less than 3% equivalent interest rate
No security deposit
No up front cash (only 1st month's payment and sales tax if applicable)
Residual will depend on lease term. (Between 58 and 68%)
NEGOTIATE SALE PRICE 1st.
Don't forget the various incentives BMW is currently offering.
