Your lease will be based on the expected depreciation of the car. A higher residual value (or "expected" resale value) at the end of your lease term will result in a lower lease payment. Most people just focus on the lease rate, but the residual value is just as important.

That's why it's nice if the dealership will lock in a residual value for your car when you order because the residual will most likely have dropped in the 3-4 months you will have waited for delivery of your car.
