The Repossession Finance Company (RFC) had a perfected security interest in Hattie Mobile's car (RFC's lien was noted on the certificate of title as required by state law). The car broke down on the interstate one day, and Hattie had it towed to Mike's Greasepit Garage, where it was repaired. State law gave a possessory artisan's lien to repairpersons. The garage told Hattie it was claiming such a lien, but when she pleaded with the manager, he let her drive the car to work after she assured him that she would return the car to the garage for storage every night (fortunately, she lived across the street). Repossession found out about this practice and, deeming itself insecure (§1-309), accelerated the amount due and repossessed the car from the parking lot in front of Hattie's place of business. Which creditor has the superior interest in the car under §9-333?
