What does 'Survivor Car' Mean?
Unless the car is now tin cans, technically it is a survivor.
Another one is "Barn find", with the rust and rot on some of those it has never been in a barn or any other shelter for that matter.
They are all just advertising phrases misused and abused to sucker somebody into thinking the car is something special. I don't even open an ad if one of the catch phrases are in the title. I saw a list somewhere that gave them funny definitions.
