So, I also posted this question on Edmunds.com at the same time I posted on here, as I was doing a wide search. The host of the forum on Edmunds.com just posted this reply:
BMW Financial Services' October buy rate lease money factor and residual value for a 24-month lease of a 2011 335xi Sedan with 10,000 miles per year are .00185 and 67%, respectively for consumers who qualify for its top credit tier.
This pretty much confirms the MF, but he is saying the residual for 24mo/10k for a 2011 E90 335xi is 67%, not 69% as jopa489 previously posted. Do you know which value is correct? 67% does seem low for 24mo/10k on a 335xi.
