Use bmwconfig.com to play with the numbers but the money factor is .00125 and residual of 62% for a 36 month lease with 10K miles. Get them to explain why they are pushing you to a 39 month lease.
Hopefully you aren't dealing with one of the dealers down here in Miami. They DO NOT negotiate.
I just got a car for my wife at Ft Lauderdale BMW on Federal hwy at a few hundred over invoice with base MF and residuals.... and this was an ordered car.
PM me if you feel like giving it another try with a new sales person.
