LIRacer - may want to try posting this on the BMW forums over at Luxury4Play as well. There are some big spenders on that forum and I've seen people take over leases on Masseratis etc.
Re: lease liability assumption - bmw financial passes the full liability along to the new lessee. alot of other auto financiers don't. i can complain all day about bmw dealers and their crap service departments, but i have to admit that bmw financial is one of the easiest to deal with out of all the mfgr's in house financial departments. their loyalty rates are excellent and the ability to purchase more miles so easily is something i haven't experienced before.
