I think, a few years ago (
), this was meant for carblueprints, and thus for carmodeling. But since the forum grew, and grew, and grew, and the blueprints became submarine/boat/plane/motorcycle/etc's, why not let people post their non-car models too? If you're only interested in cars, just check the cars only.
A forum is a forum.. A place to discuss.. even if it isn't a car.
My opinion..
