Auto GB sounds like a good idea. I don't think I would have time to get involved. But for my two cents. Why not just throw the GB open to build a car, any type of car - race car, plain jane out of the box, etc. Racing cars could scare some off, especially when they are trying to duplicate the colours, put on mega decals.
Wet the interest just build a car. Maybe a person would like to build just a car with no fancy frills, or they may like the looks of a particular model - mustang, t-bird, 50's 60's vintage or maybe they like the PINTO . No need for a fantastic pristine paint job, just have fun.
I'm not the fastest builder, nor the sharpest builder, not the best painter, but I am having some fun.
Boogity, Boogity, Boogity, lets go building.
Ah what the heck make it a year long GB - Auto GB 101 and I might be tricked into joining.
