Those numbers don't make sense unless you're doing a $2,200 down payment (cap cost reduction). Is that the case?
I'd say forget the down payment and live with a slightly higher monthly. Without a down payment, the monthly should be $683+tax.
Also, if you plan to potentially buy the car after the lease is up, I'd suggest you get some options on the car. It will help resale value and marketability significantly. If you're not going to keep the car, then it makes no difference.
