"Amount financed" means the cash sale price of the motor vehicle plus all other charges individually itemized, which are included in the amount financed, including the amount actually paid or to be paid by the seller pursuant to an agreement with the buyer to discharge a security interest, lien interest, or lease interest on the property traded in, but which are not a part of the finance charge, minus the amount of the buyer's down payment in money or goods.
