Sec. 233b. (1) As used in this section:

(2) Except as provided in this subsection, a new motor vehicle dealer shall disclose in writing to a purchaser or lessee of a new motor vehicle, demonstrator, executive or manufacturer's vehicle, or program vehicle before entering into a sales contract or lease agreement that, after the vehicle completed the manufacturing process, the vehicle was damaged and repaired, including an itemization of repairs, if the dealer has knowledge of the damage and repairs and if the cost of the cumulative repairs, as calculated at the rate of the dealer's authorized warranty rate for labor and parts exceeds either 1 of the following:

(3) A dealer in new motor vehicles is not required to disclose to a purchaser or lessee under this act that any glass, tires, wheels, bumpers, audio equipment, in-dash components, or components contained in the living quarters of a motor home that are not required for the operation of the motor home as a motor vehicle were damaged at any time if the damaged item has been replaced with original manufacturer's parts and material.

(4) Repaired damage to a motor vehicle, subject to this section, not exceeding the cost of cumulative repairs as determined pursuant to subsection (2) shall not constitute grounds for revocation of acceptance by the purchaser or lessee. The right of revocation ceases upon the purchaser's or lessee's acceptance of delivery of the vehicle.
