I have been looking diligently for a new used vehicle for months and this I noticed over and over. If you use the used car formula from when a vehicle is newly purchased apply the industry depreciated value formula, then reapply the used vehicle formula for resale those figures do not add up back to the dealership resealing a used vehicle, only when a person trading their vehicle into the dealer to buy a new vehicle. Which from what I have researched is always a poor money investment when it come to depreciated value once signing the contract. Used vehicle sale people play the dealership games
