No way am I selling my own car. Dealing with someone else’s financing paying off my financing. Letting people drive it around. Potentially sitting on it for months, losing money ever second it sits there. No thank you.
The first problem is automatically avoided if you didn't finance your car in the first place, as I am suggesting. For the rest, if you drive your car until it has lost all value, which is what I do, and typically takes 20 years, then there's no further loss of value no matter how long it sits, and the risk from people driving it around is also lowered. If you really don't want to go through any hassle, then just sell the car to a junkyard as the dealer won't offer any meaningful trade in on a junk car anyway.
