Ok, I found the original ad on ebay. It sais:
FERRARI 212 Inter Europa Pininfarina Scocca Originale Epoca 1953 Auto Bicicletta
Telaio del 1953 FERRARI Pezzo unico introvabile e raro
Claimed to be an original Pininfarina body for a Ferrari 212 Inter Europa (?!) from 1953 but now fitted on a new "bicycle" chassis. I prefer not to comment the absourd description. And I prefer not to think if there is people who believe to such a ridiculous ad... and pays 30.000 € for this almost surely fake Ferrari pedal car!
