Phil in your opinion and in todays world what % does the COPO option tack on to the price of a fully restored Z?

First you have to want one and to many the '70 just does not look like a '70 without the standard short RPO Z28 spoiler.
But if you do want a real COPO 9697 and if the car has good history, documentation options and colors perhaps 50% bump in value.
I am going on what I was offered for mine compared to a simular optioned ( good resto-same color combo and a 4 speed) Standard Z-28' sale that was completed almost two years ago.
