I am considering purchasing my own soon-to-come-off-lease 2005 X5 - but the residual value is ridiculously high considering the current market value for these vehicles (around $36k). Does anyone know if BMWFS offers any incentives (i.e., discounts from the residual value) to encourage the purchase of these vehicles? If so, how much and what is the best way to negotiate such a discount? Thanks.
