Not enough younger people in this hobby...

You could always buy them a car and show them how to work on it. That is till their mother raises the safety flag and higher mpgs and less maintaining and I could go on but you get the idea. Me I'd guide them in picking a modern car and showing the basic they can do themselves. This way they get a feel for cars but more importantly that get to save money for school. College aint cheap and while in college you generally can't afford a project car anyway.
