Why do some car listings have titles with liens on them?

When a vehicle that was financed is paid off the bank or finance company does not report to DMV that the vehicle is paid for. So the lien information stays in the DMV system until either the owner takes the title to their local Motor Vehicle Agency to show them the vehicle is paid for or when the vehicle is sold. For example my 2008 Grand Marquis has been paid off since 2016. But if you run the VIN you will see the vehicle still has a lien on it. Why? Because I refuse to go to DMV with the title and report it's paid off. I don't think it's my job to do that! That, in my opinion, should be required of the finance company. When the vehicle is sold the information will be updated. Hope that helps! Jim
