“Built from Bizzarrini parts, the Manta was one of Giorgetto Giugiaro’s first independent designs as an independent consultant. He used it to promote and launch Ital Design in Turin. The Manta is remarkable as it was built up from an ex-Le Mans racer and it is one of the first cars the world to use a triple seat arrangement.
Inside the cockpit is an odd layout that seats the driver in the middle of the interior with a passenger on either side. The idea was copied from a Ferrari 365 prototype built in 1965 and it was later, more popularly revived with the mighty McLaren F1. With three people seated side-by-side it must be a particularly tight squeeze as much of the available passenger foot space is occupied by intrusive wheel wells.”
