I normally don't step into these threads because I don't know any of you and don't want to step on anyones toes.
But, this thread seems to be discussing the kind of problem lots of people would like to have... which one and how much, how many, documented, etc...
I for one would love to have a COPO, Yenko, LS6 Conv, L89 Conv, Motion, etc... and I believe that they are worth a great deal of money. Can I justify that kind of money to my wife and family? Probably not. (If someone wants to sell one that needs a good "no resale" home at a below market price please e-mail me

)
Do some people use them as investments? Yes. Do most people that own them enjoy them? Yes.
The bottom line is a car, or anything else for that matter, is only worth what someone is willing to pay for it.
Those with Champaign wishes and Caviar dreams will be able to own some of the greatest cars ever made is America, while those of us with a Miller and Steak will watch from behind the wheels of our SS Chevelles, Camaros, Novas, etc...(also great American made classics).
Hope that I didn't ruffle too many feathers. This hobby should NEVER be about the "haves" versus the "have nots". In the end, we're all car guys that can hopefully appreciate each others rides without too much envy.
