It would seem that back in 1978, Swiss "car designer" Franco Sbarro spent nearly the entire year under the influence of powerful narcotics. That's the only sensible explanation for the six-wheeled rolling abomination that he managed to create that year. Called the Sbarro Function Car, ironically, the leviathan was based on a lengthened Cadillac Eldorado and weighed over 3 tons. It was powered by a 350 horsepower 8.2 liter V8 mated to a four-speed automatic transmission.
The car was commissioned by Joseph E. Adjadj, a wealthy Saudi Arabian businessman and owner of TAG. He wanted a mobile office with all the luxuries of a home he'd never heard of an RV. Or good taste.
On the inside, the Sbarro Function Car had four large armchairs - not including the driver's seat, two telephones, a TV, and a refrigerator. It also had fold-down office desks and luxurious wood paneling.
The ultimate goal of Sbarro and Adjadj was to build 25 cars and market them to on-the-go business leaders of the time. Thankfully absolutely nobody was interested, and the project was abandoned after just one car was built.
