(d) A participating county shall provide an electronic means for distributing vehicle repair or replacement funds once all program criteria have been met with regard to the repair or replacement. The county shall ensure that funds are transferred to a participating dealer under this section not later than the 10th business day after the date the county receives proof of the sale and any required administrative documents from the participating dealer.
(e) In rules adopted under this section, the commission shall require a mandatory procedure that:
(1) produces a document confirming that a person is eligible to purchase a replacement vehicle in the manner provided by this chapter, and the amount of money available to the participating purchaser;
(2) provides that a person who seeks to purchase a replacement vehicle in the manner provided by this chapter is required to have the document required by Subdivision (1) before the person enters into negotiation for a replacement vehicle in the manner provided by this chapter; and
(3) provides that a participating dealer who relies on a document issued as required by Subdivision (1) has no duty to otherwise confirm the eligibility of a person to purchase a replacement vehicle in the manner provided by this chapter.
(f) In this section, “total cost” means the total amount of money paid or to be paid for the purchase of a motor vehicle as set forth as “sales price” in the form entitled “Application for Texas Certificate of Title” promulgated by the Texas Department of Motor Vehicles. In a transaction that does not involve the use of that form, the term means an amount of money that is equivalent, or substantially equivalent, to the amount that would appear as “sales price” on the Application for Texas Certificate of Title if that form were involved.
