Can you sell a car to dealership if your loan was charged off and you a have a lien on the title?

At minimum, you must satisfy (pay off) the lien. Talk to a dealership---NOT the one you plan to do business with, but call a different one---they can give you information. When you go to sell the car, keep in mind the lien amount in your overall price you want for the car. Make sure you get paperwork when you pay off the lien.
