Now, all this being said, it's unlikely that you'll lease through your bank. A Lexus or an SUV or some other vehicle with an insanely high residual, maybe, but not a Saab.
Most carmakers boost the residual of a model to make it more attactive.
They also sweetened the pot with a very low money factor, which is pretty much the APR on which your depreciation will be calculated. This all assumes that there is a national program for Saabs right now. When I decided to lease, I narrowed my choices down to a few cars, and waited until a killer lease deal arose from the contenders. Anyway, good luck, read up on the background information, wait for a good deal, and don't let the salesman snow you. Walk in informed, with knowledge of a national program, and they generally drop the BS and start treting you like a person.
