So, has anyone had luck negotiating w/BMWFS on lease end buyout?

[X-cellent]

I had been contemplating an X5M, but the new business is still a little too "young" and fragile to burden with that big a number right now for my car...I know all the financial ramifications, but the long and the short is I could lease a new 3.5d, find a less expensive alternative (one thought is to buy something inexpensive to drive for a year or two then give it to my son when he turns 16), or buy my X5 out of the lease. Stated buyout is $43k, vehicle has 21k miles on it.....

I am very particular, and the X still looks brand new (other than needing a new rear bumper skin thanks to some parking-lot-shithead)...

Financially I was going to cut back and get a lesser vehicle for the next two years or so, but don't know what I could drive and not have the urge to drive it into a tree..need a largeish vehicle for kids, sports, travel, and live in a neighborhood that resembles a waterpark in the summer with flooding.....

Just wonder if anyone has had luck w/ BMWFS and negotiating a better buyout than whats stated on the lease....
