1. When a motor vehicle, trailer, boat or outboard motor for which all sales or use tax has been paid is replaced due to theft or a casualty loss in excess of the value of the unit, the director shall permit the amount of the insurance proceeds plus any owner’s deductible obligation, as certified by the insurance company, to be a credit against the purchase price of another motor vehicle, trailer, boat or outboard motor which is purchased or is contracted to purchase within one hundred eighty days of the date of payment by the insurance company as a replacement motor vehicle, trailer, boat or outboard motor. As used in this section, the term “boat” includes all motorboats and vessels, as the terms “motorboat” and “vessel” are defined in section 306.010.

2. If the owner of a motor vehicle, trailer, boat or outboard motor as described in subsection 1 of this section does not have insurance coverage for the motor vehicle, trailer, boat or outboard motor, the director shall permit the fair market value of the motor vehicle, trailer, boat or outboard motor as determined by the Kelly Blue Book, NADA Used Car Guide, Abos Blue Book or the average of two appraisals from licensed motor vehicle or boat dealers to be a credit against the purchase price of a replacement motor vehicle, trailer, boat or outboard motor which is purchased or is contracted to purchase within one hundred eighty days of the date of such loss as certified by a law enforcement agency or such other evidence as the director may require as proof of the date of loss of the motor vehicle, trailer, boat or outboard motor.
