Jones bought a used car from the A–Herts Car Rental System, which regularly sold its used equipment at the end of its fiscal year. First National Bank of Roxboro had previously obtained a perfected security interest in the car based upon its financing of A–Herts’s automobiles. Upon A–Herts’s failure to pay, First National is seeking to repossess the car from Jones. Does First National have an enforceable security interest in the car against Jones? Explain.
