Sorry to bump an old thread, but model cars are one of my hobbies too.
I'm currently building a 1/12 model of the Mustang from Gone in 60 Seconds. It's subscription-based. I get a couple of shipments a month, each containing some component of the model to assemble.
I also have a fairly good sized collection of 1/18 and 1/64 scale cars. I'm told one of my relatives also loved models, and I saw some of the ones he built. They were in my basement, but I don't know if I have them anymore.
