Future of the classic car hobby may be unstable per experts?

My 13 yr old Grandson loves my Demon and would like to have it and even asked me if I would give it to him when he turns 16. He is my Daughter's son and my Son in law who is 39 yrs old would like to have it when I kick the bucket. My Son (36 yrs old) would like to have it also as well as his son who is 9 yrs old. My Son in law likes to work on cars but my Son does not. I am inclined to give it to my Son in law when I am gone because these cars need periodic work done on them. My Son just would want to to drive it and when it had a problem would probably just get rid of it. I think it may be true what others have said about young people not having an interest in these cars is because of little exposure to them. The young guys in my family all seem to want mine.
