I think most of us are talking about leasing not buying.People have to stop buying lease payments and start buying a car. A lease is just a form of financing. Buying a car is actually three transactions: (1) sale of trade-in; (2) purchase of a new car; and (3) financing the purchase. Negotiate each separately and you will be able to get the best deal. Allow the dealer to roll all three together, and you have no idea whats going on and will not get the best deal. Simple as that.
If buying then you are correct.
Button line is either way you end up with a vehicle.
