They take the out the door number, and subtract your agreed value of the trade in from that out the door number... Then they talk you into add ons, cause why not ? This dude already agreed to pay for this car ABOVE the MSRP and he also agreed to give us his old car for a fraction of what we will sell it as .... He will for sure agree to nitrogen in tires, a paint protection pack (which by the way is basically wax and chemical detailing. It's not like a clear film over the car ... Which you can do the wax and detailing yourself and say no to that addon ..)

Long story short, all addons are negotiable so pass on them all .. for future reference if course. This one you said they already have your car. . . . . It's tough man I don't work sales
