From eBay listing:
George Barris Car. This is one of the cars used in the 1994 live action feature film Flintstones based off the cartoon show. This is a Barn find and needs a full restoration
It is the Flintmobile and, yes, George Barris designed it. Serial number 10,000,000 BC (not really). Ironically it's powered by electricity, not footwork. It is based on an electric golf cart.
It is amazing how much attention it draws even in the condition it is in.
I really hate to sell it but need the room.
The body is on a rollable cart and can be put in a transporter with the cart.
