Civ. Code, § 3074

The lienholder may charge a fee for lien sale preparations not to exceed seventy dollars ($70) in the case of a vehicle having a value determined to be four thousand dollars ($4,000) or less and not to exceed one hundred dollars ($100) in the case of a vehicle having a value determined to be greater than four thousand dollars ($4,000), from any person who redeems the vehicle prior to disposal or is paid through a lien sale pursuant to this chapter. These charges may commence and become part of the possessory lien when the lienholder requests the names and addresses of all persons having an interest in the vehicle from the Department of Motor Vehicles. Not more than 50 percent of the allowable fee may be charged until the lien sale notifications are mailed to all interested parties and the lienholder or registration service agent has possession of the required lien processing documents. This charge shall not be made in the case of any vehicle redeemed prior to 72 hours from the initial storage.
