Bodybuilder Boneschi presented a prototype 3500GT at the Turin Motor Show in 1962.

It has the same technical characteristics as the other 3500GTs, the 220 hp 3.5-litre L6 as its centrepiece.

The very futuristic corner design of this model is completely against the current stylistic trends of the time which favor curves.

In 1963, the model evolved slightly, in particular the wheel arches and the air intake of the hood, but kept its taut lines perhaps too ahead of its time because only one was produced.
