Probably in the 80's, I stopped at a gas station for gas. Parked next to the gas pumps was a 1956 Chevy, with a 1956 Pontiac, attached to it, facing backwards.
They were spliced together. Both cars had steering wheels. I couldn't get any information, because the owner wasn't there. However it was done, was pretty Kool.
To make it even more puzzling, they were both painted different color's.
