Pininfarina X Concept Car from 1960

The Pininfarina X first time appeared in 1960. 

The Pininfarina X-Concept was introduced as a pure design study and took a unique approach to laying the car out, with one, steered wheel up front, two outrigger wheels at the side, and one powered wheel at the back. A mighty 43 horsepower four cylinder Fiat engine brings the power and a four-speed manual transmission keeps things properly sporting. The X-Concept's extremely cab-forward design is balanced by its towering fins out back. Now you can find this car on eBay and starting price is set to $800,000.
