The price of the car and the reupholstery alone you could turn around and sell it for alot more then the money used to fix it.
Cost around 2500 total
Turn around sell for around 4000-5000.
Nice profit.
Just don't mention the background.
Oh and be sure to get a copy of the tape, and give him a fake name and everything so that they can't come back to you when they figure out what the car had been used for. [:0]
