Original Paint Depreciation

[70-SS/RS-L78]

I have a 1987 GNX that has 1075 Miles on her and she still has 100 percent of the original paint and it is in extremely nice condition. If for some horrible reason I would have to paint this car or even a few panels it would depreciate the value. Original paint GNX’s are hard to find. Most were repainted due to the horrible finish GM put on these cars when they built them.. Is there a policy to cover the depreciation of a survivor collector car that has to be repainted due to an accident or if some IDIOT keys the car while at a show. I know they will pay the repair claim but what about the loss of value due to the repaint?
