Hey,
I have some experience in this situation so I hope my advice will help here:
I used to have that 03 VW Jetta and I had that piece of shit for a year, and it was in a 3 year lease. You CAN do the leasetrader thing, and I was gonna do that as well, but be aware that it's not as simple as finding a credit-worthy person and transferring the lease. The personal who originally leased the vehicle, his/her name is still on the lease contract, even after the lease is transferred. So if this new guy fails to make any lease payments, BMW will go after the original guy for those payments!
Another option is to just privately sell it or trade it in and pay the difference of the buy-back value. For example:
On my VW Jetta (I used to have a 03 Jetta, for those of you who don't know), I put nothing down, aside from inception fees. My lease was for 3 years, 36,000 miles, $0 down, taxes included, etc. I got rid of that bastard 11 months into the lease because I hated it so much. The way I did it was, I called up VW and found out the buy-back value at the current time, which was $17,366. The Infiniti dealership was offering $14,000 for the trade-in value. So, I handed my Jetta over to my Infiniti dealership + $3,666 difference ($17,366 - $14,000)...dealership took care of all the bullshit paperwork for me (otherwise the process takes about a month!) and I was in my new car, literally as soon as I handed over the keys to the Jetta.
Thanks,
