The car was owned by a Sheriff, and not Dillinger. He stole it from her during a prison break. Are you going to pay the bills to destroy someone else's car, because you don't want to have any memory of Dillinger?
The story is amazing. The fact that the car somehow still exists after all this time and the events surrounding it is nothing short of a miracle. This car definitely needs to be preserved! Also such a good looking body style on that car.
