About this time Lamborghini started to get interested in developing a high performance car. He had owned Oscas, Maseratis and Ferraris but was always disappointed with them. Particularly their engines. There is a now famous story about how he was frustrated with problems he had with a clutch in a Ferrari (a Ferrari 250 GT), and went to visit Enzo Ferrari who's factory was nearby. Enzo had no time for a tractor manufacture and simply dismissed him. Lamborghini decided there was nothing Ferrari was doing he could not do better. He decided too build his own car with a V12 engine. For the design he found a very talented engineer named Giampaolo Dallara who had previously worked on a Ferrari V12 engine.
