I have a 36 month lease on a pretty loaded jet black 2008 535i that i got delivered 6 months ago. It only has 3500 miles on it but I want to make a switch to a 3.0 X5. Will the dealer be willing to let me transfer my lease payments over to the X5? Or will swapalease be a better option? I put 7000 down at signing. If it makes any difference I also plan on buying a mini from the same dealer later this year, do you think that would be incentive for them to let me transfer?

options are as follows:

jet black
natural brown
bamboo
premium
sport
ipod/usb
premium sound
anthracite headliner
HUD
active steering
NAV
PDC
