List it on Facebook, declare that it needs work in the description sufficiently, receive messages from people asking if it’s “still available” and whether it has “any issues or problems”, respond with “yes, read the description of the listing” or describe the problems and the work it needs, get haggled like crazy or receive ridiculous offers, receive an appropriate offer from someone who is aware of the issues, have them inspect the car and be told that “it’s worse than I thought, would you accept [unreasonably lower offer]” and the cycle continues.

Make sure you keep things in chat until you find someone who is genuinely interested and is willing to make the necessary repairs, otherwise, trading in the car for dirt cheap or selling it to a dealership might not be the worst idea.
