I'm a bit surprised at all of the banter in this thread. Opportunities to assume one of the "fire sale" leases from last winter don't come up real often, let alone on a car with a color combo and options as sweet as this one and that appears to have been extremely well cared for. A new '09 model specced out like this car would lease for about $1200/mo right now with nothing out of pocket.
If I was in the market for an E90 I would have already submitted the credit app to BMWFS on it. I expect the OP will have a taker in a matter of days, if he doesn't already, and I'll offer my congrats to the new owner.
OP I'm sorry to see you parting with it, hopefully there's something better in the pipeline for you.
