Future of collector cars

I have a ‘73 Dart Sport and ‘73 Duster. I told my son I was leaving them to his two boys, he said the hell with that, those are mine. When I told him I was going to buy another Vette, he asked new or classic, I told him new. He said that was more my thing than his. He’d rather have a classic. My nephew has a ‘69 Road Runner sitting in his shop to restore. His younger brother has had more muscle cars than I have. I see it slowing down some, but not going away.
