FYI - A dealer bought out my leased BMW vehicle above the residual (almost the same amount as your residual). The amount paid above the residual was applied to the new vehicle purchased. My 7 MSD's were returned by BMW financial about 2 weeks later by check mailed to me. The dealer charged me the $350 disposition fee that was subsequently waived by BMW (though the new vehicle is not a BMW). I believe I got a good deal and did not pursued the $350 from the dealer.
