This is where it all began for Lamborghini. Designed under the guidance of chief designer Gianpaolo Dallara (of Dallara Motorsports fame), the 350GT was Ferrucio Lamborghini's rebuttal to Ferrari over his dissatisfaction of their vehicles at the time, most notably due to their lack of creature comforts. He sought to create a more comfortable touring car with a sporting edge. The original 350GTV prototype used a variation of the Bizzarini designed 3.5 liter V12, which developed 400 horsepower at 11,000 rpm; astronmical figures for the day.
Practicality won in the end, and the 350GT had a detuned 270 horsepower V12. The bodywork was handled by Carrozzeria Touring, who fabricated the body structure using their Superleggera, or "Super Light" method of attaching aluminium panels to a tubular structure. Here's a 350GT for sale in Kentucky looking rather sharp with it's black on tan color combination.
This 1966 Lamborghini 350 GT Superleggera Coupe features a 270hp 3.5L V12 engine. It is equipped with a 5 Speed Manual transmission. The vehicle is black with a tan leather interior.
To get a short idea of just how sonorous this Lamborghini is, here's a short clip of an example auctioned by RM in late 2008.
