You will have to negotiate sale price and Money Factor (interest) with the dealership. You can put up to 7 security deposits to lower your MF by 0.0007 each. One security deposit is equal to one monthly payment rounded up.
I just negotiated a 2013 X5-35d with MSRP 65k for around $870/month with a 15k/year lease. 12k/year is about $30/month cheaper. I kept asking myself what is my exposed risk over 3 years; 35 x my monthly payment (first payment is covered by a rebate) so basically $30k or 10k/yr. Leasing might not be for me, but I'm giving it a try to find out.
Sorry to hear about your dislikes on the 35d. I'm super excited to get into one after test driving a few. I know the mpg advantage is almost a wash with higher cost for diesel. I'm happy with a lease, the residual is set and I don't have to put away 65Gs for 3 years (assuming I would buy the car outright). I considered financing but with the new X5 model arriving 2014 I have the options to 'upgrade'.
