My deal started with a base rate of .0013, and I got .00049 off for each of my seven security deposits, which brought the rate to .00081. A rate of .00116 after seven security deposits seems way too high.
Separately, it's easy to compute your own lease payment, so you can see the effect, for example, that a reduction in the MF would have. I think there is at least one thread at Bimmerfest that tells you how to do it. For what it's worth, however, if my MF had been .00116, my payments would have been about $30 a month higher, so not trivial.
