between now and the end of the year you can do better. Its a national program and ATL is the most competitive area for Nissan in the country. If you really want a 3yr lease, have them waive the $2k down and bump to 15k per year. That would be more in line.
Also, I'd really never suggest putting money down on a lease. Ever. Even if you raise your payment, keep your cash and realize you'd be paying that anyways.
just my .02.
