Automaker leases are sometimes subsidized, or "subvented."The automaker can take money off the top, with an extra rebate just for lease deals, or it can raise the residual, or both.
Okay, fine. But what if I’m overmileage and want to cancel my lease to buy out my car early? Again, bad idea. In all honestly, you end up paying for overmileage no matter which way you look at it. The reason overmileage is an extra cost at all is beause you are driving the car more and therefore making the car depreciate in value.
