The seed for Lamborghini: A broken clutch in Ferruccio Lamborghini's Ferrari.

The story or the tale that is responsible for the foundation of the firm named Automobili Lamborghini S.p.A. or simply Lamborghini is not known as a famous tale, but it is quite an interesting thing that drove Ferruccio Lamborghini to set-up a firm  with the objective of producing a refined grand touring car to compete with offerings from established marques such as Ferrari.
Ferruccio Lamborghini, the man who found Automobili Ferruccio Lamborghini S.p.A. in 1963, was the child of viticulturists living in Renazzo di Cento, Province of Ferrara, in the Northern Italy's Emilia-Romagna region. After serving as a mechanic in the Italian Royal Air Force during World War II, Lamborghini went into business building tractors based on surplus WWII military hardware. By the mid-1950s, Lamborghini's tractor company, Lamborghini Trattori S.p.A., had become one of the largest agricultural equipment manufacturers in the country(Italy). He was also the owner of a successful gas heater and air conditioning manufacturer. 
Lamborghini's wealth allowed him to cultivate a childhood interest in cars, owning a number of luxury automobiles including Alfa Romeos, Lancias, Maseratis, and a Mercedes-Benz. He purchased his first Ferrari, a 250GT, in 1958, and went on to own several more.

Lamborghini was fond of the Ferraris, but considered them too noisy and rough to be proper road cars, likening them to repurposed track cars.When Lamborghini discovered that the clutch on his Ferrari was broken, and actually was the same clutch that he used on his tractors, Lamborghini went to Ferrari and asked for a better replacement.
Ferrari responded, saying that he was just a tractor maker, and could not know anything about sports cars. Lamborghini decided to pursue an automobile manufacturing venture with the goal of bringing to life his vision of a perfect grand tourer.

Lamborghini designed and built the Lamborghini 350GTV  in only four months, in time for an October unveiling at the 1963 Turin Motor Show.

Lamborghini as a firm has seen alot of ups and downs during its journey.Lamborghini's ownership was transferred to many owners, starting from 1971 to 1998 Lamborghini has seen many owners and finally Lamborghini was acquired by Audi AG in September 1998.

By technical expertise and brilliance Lamborghini has produced revolutionary sports cars like Countach, Diablo, Gallardo(baby Lambo) and many more. 
So this was the tale of Ferruccio Lamborghini and his firm.
