This 1932 Ford Gravity racer is the kind of a soap box derby racer you would have built when you were a kid if you had the time, money and know how. A hand laminated epoxy and fiberglass body has a mild steel chassis and an aluminum belly pan. It has rack and pinion steering plus 4 wheel disc brakes.
The molds used to create the body are included in the sale so you can be sure no one else will have one, unless of course, you decide to make more yourself, which could be an interesting little business.
Although this is a gravity racer, just think if you installed a tiny little engine of some sort or maybe an electric motor. Your kid would be the envy of the neighborhood.
