A charge off already sounds like an error on their side. I would just keep on to it until they contact you. It is their burden to retrieve the car or make arrangments for you to drop it off. Whatever you do, I would not try to sell the car or get rid of it because they will have rights to go after you for the cost of the car if they realize their mistake. Also keep in mind how long it's been. While it may seem odd loan companies often move very slowly with this sort of think. It can be year or more before they get around to repossessing it. Either way I'd keep the car and use it until the do.
You can get arrested and charged with vandalism
I don;t know what you mean by "Charged Off". Unless somehow they have written you off as a deadbeat and forgotten the car, which I doubt, they will come and get the car. They will then sell the car and you will pay the difference in what the car sold for and the balance on the loan. Your credit will be ruined for 7 years.
If the loan on your car was charged off then the lender has written it off as a loss. You can still renew your registration. It surprises me though that a lender would charge off a secured loan.
They'll be arrested and charged.
If it was found anywhere near the area in which you were seated you can be charged with possession.
You hope they just take the car. You can be charged with a crime in many states.
You can still have it ,but you will be paying heavily for it and have no resale value for it.
it will not work
Pay it off. It will still likely be repossessed.
It goes to collections. If you are still in possession of the car after you agreed to return it, then it will be reported stolen, as in "theft by fraud." First they max out your cc during the process of reporting it stolen. (Embezzled) If caught in the car you will be charged to GTA and rental companies almost never drop the charges.
It would depend on your definition of "while". All car batteries will go flat if not charged for very long periods of time.
