I'm 32 and have always had old cars, it started with a 67 chevelle that I still have, and has progressed over the years into E bodies, a 70, 71, and 73. I also have a 56 F100 and a 56 chevy bel air that my dad has given me. Also a 70 Duster tube chassis race car( this runs great). None of them are running/driving as I have 2 young kids 4/2 but I am always working on cars and stuff around the house. I think the majority of the problem is that kids are given video games and never shown anything that is truly fun. My son already can identify a Cuda in his hot wheels collection and I have been talking and showing him jr dragsters since he was 2. His sister and him have been driving a power wheels for years at this point, in the next few years I will pick up a jr and he will start racing it just like other kids play soccer or baseball. Hopefully he will be interested in cars as it is my only interest. Weather or not this translates into what the value of the cars will be in the future, I am not really concerned but I have bought and kept the 70 and 73 for them if they show an interest in them
