I am interested in taking over a MB lease, however I've in the US for not so long and won't any credit file here, I will be able to pay all the remaining payments in cash upfront.

Any ideas on ways to accomplish this?
I called MB finance today, they surprised by their answer "simply don't know".

Any previous experiences on that subject? I know some other manufacturers have programs for first time buyers... but don't if MB has such a thing.
