This doesn't include sales tax or TTL as these numbers will differ a lot based on your location.
You cannot negotiate residual value or MF, but you can and have to negotiate Cap cost. The lower you can get it, the lower your payment will be. Don't put anything towards your down payment, these money are lost if your car is totaled.
