The abandoned vehicle or abandoned automobile hulk shall be sold at such auction to the highest bidder. The proceeds of the sale, after deducting the towing and storage charges due the tow truck operator, including the cost of sale, which shall be computed as in a public auction sale of personal property by the sheriff, shall be certified one-half to the county treasurer of the county in which the vehicle is located to be credited to the county current expense fund, and one-half to the state treasurer to be credited to the highway safety fund. If the amount bid at the auction is insufficient to compensate the tow truck operator for his towing and storage charges and the cost of sale, such tow truck operator shall be entitled to assert a claim for any deficiency, not to exceed $100.00, less the amount bid at the auction, against the last registered owner of such vehicle or automobile hulk. (Added by § 15 of Res. adopted June 15, 1970).
