For me, model building has been a way to have the types of real cars I'd own, if I were rich. And I've always had the space for lots of models, whereas, what would I do about parking a bunch of real cars? Building models has allowed me to learn about things that I never thought about too much otherwise. Things like mechanics, art ( colour, form etc.), and thinking things through to achieve a finished car. That's why scratch building appeals to me. It's good for the brain to figure stuff out, without an instruction book. And ultimately, all these thoughts may just delay the dreaded alzheimers, just being creative. Sure would be nice to bring some kits to "the home" LOL.
