$82,000 for the 3/8ths scale woking model of the 1956 Pontiac Club de Mer, it was in the motorama along with the full size concept; but after the show circuit, the head of design, the legendary icon Harley Earl, had the Pontiac mechanics give it the controls and electric motor apparatus for full functions. He then gifted a grandson with the kiddie car, very cool.
