how does it work when you sell a car?

[brs]

so i know how it works when you trade in a car, what about when you sell a car. im sure you prolly could make more sellin it yourself then to a dealership. but after that what happens? is you loan paid off, are you done with it when you sell it to somebody else? im sure this is a stupid question but ive never sold a car before.

so say you sell a challenger rt for 32000. do you still need to pay off what you owed on your loan from what you made sellin the car or does it just go to whoever buys the car
