Bizzarini P538
Probably one of the most expensive Lamborghini models in existence are these P538, in fact this is a car that wasn’t built at the Lamborghini factory but by one of the people who were there in the very early days, Mr. Giotto Bizzarrini himself. The latter designed the engine for the 350 GTV, and detuned it afterwards to fit the 350 GT needs of a quiet Gran Turismo. After that, Giotto Bizzarrini worked with Renzo Rivolta on his ‘Iso’, but later decided to build a race car, this became the P538.
