future value of classic performance cars,when to bail out, before the crash?

It's not about the money for me I really don't care what there worth, its the nostalgia, I had so much fun with them when I was young and they were cheap. But that's really what have drove the prices up, everybody likes to re live their youth and these cars remind us of the good old days, now there's less of them to go around. Now most of us are older and retiring and have a little money to spend on one and it drives the prices up. Now that the baby boomers are older we're starting to die off and day by day the prices will level off. Just like us we would rather have a model A hot rod than an original one, younger generations will probably rather have restomod muscle cars than original. Now generation x is getting older and Fox body mustangs and IROC camaros are gaining in price. Our beloved Mopars will be leveling off in the next 10 years I believe. I'm thankful to have the privilege to have lived through the muscle car years and although a Mopar fan I love them all, stock, hotrod, restomod and all.
