In general, a can collector would not have standing to file a civil suit for repossession of a vehicle, as they are usually not the legal owner of the vehicle. Repossession is typically an action taken by a lender or creditor who has a security interest in the vehicle, such as a bank or credit union that provided a loan for the vehicle.
If you are a can collector and believe that a vehicle is being wrongfully withheld from you, it is advisable to consult with an attorney to understand your legal rights and options.
