I am not an expert by any stretch but here is my perspective on values of Yenko copos compared to Berger copos. I think for the most part it comes down to popularity verses rarity. Obviously the popular being Yenko and the rarer being Berger. I think yenko put a little more of their own touches on them so that can add to the value but most Berger copos were x-11's with vinyl tops and endura bumpers so that may add too. I feel one thing that has kept the Yenko's prices higher is that Berger copos are rarely seen for sale or at auction. Thus keeping the popularity down.
I also have another theory that may change things down the road. Berger is still operating and are still selling high performance cars. I have been told they have over $200 million in gross annual sales. They currently sponsor at least 4 copo drag cars that I have seen. In other words they are still active in racing and high performance cars which will continue to drive and grow Bergers name and popularity. So the million dollar question is. What is the value of a Yenko copo and what is the value of a Berger copo?
In reality it always boils down to what someone is willing to pay and this normally ends up proving most of us wrong.
