Want to buy used car
Those are just a gimmick to get you to buy a new car. Any trade in they give you will basically be added to the sale price. You would be better off selling or junking the old car and aggressively negotiating a good price for the car you want.
Agree with FoR, that "drag, pull, or tow" a trade-in dealer pitch is a borderline scam. The trade-in value they give you is baked into the financing APR, from which the dealership gets their cut up front.
