I've been saying for over a decade that B-J has ruined the 60s & early 70s era muscle cars for the average Joe.
BUT not because "rich guys" are paying too much; it's the knuckle heads that have a clapped out 307 Nova with a flat cam thinking their car is worth north of $10K because they saw a Nickey Nova sell for close to $100K on T.V. Then you combined that with the guy that always wanted a Nova SS and now has the money to build/buy one and actually pays up for the clapped out car from the craigslist clown! These guys were/are mostly blue collar Babyboomers that came into a lot of money 10-15 years ago with finally having kids college paid off, skyrocketing IRAs, and a ton of home equity. Sure they're not paying 6 figures for a car but $30-$40K for your average run of the mill BB Chevy/Mopar/Ford is common place now.
The cars the rich dudes are paying all the money for, are actually worth it; because the restoration costs are exorbitant for the level of restoration you see on the prime time B-J cars AND the production numbers of these cars are generally pretty low. And even still a CoPo Camaro is a relative bargain compared to a Ferrari Daytona! Look up some sales at

The prices will eventually fall for the common cars as the Boomers start getting their licenses yanked for poor eyesight. There's not enough Gen-X'ers in the hobby to maintain the demand we've seen for the last dozen plus years and the Millennials...well they're lusting after Teslas and the Google car. Let's just hope that driverless electric cars don't take over the roads before the Collector Car market crashes...
