Last I looked, used cars sold privately are on an "as is, where is" basis. No warranty express or implied and the condition of the car is whatever the buyer thinks it might or might not be. Given its mileage, I doubt if CarMax, a dealer or any other car buying site will take it. So no worries when selling this automobile, if in fact the OP does decide to sell it.
If it was me, I would drive it like stole it until it dies its inevitable death, and then call up the junkyard to haul it away.
