Salvatore Diomante is an automobile engineer and restorer, best known as Bizzarrini's factory manager in the 1960s.
He started his own firm in 1968; one of his first contracts involved building the AMC AMX III.
The Quattroporte offered a sumptuous interior and a correspondingly high price tag of 210 million lire.
[7] The stretched 131, called the SD 131 Diplomatic, sat on a 60 cm longer wheelbase than usual and was thus nearly 5 metres long.
[8] Diomante also constructed a stretched station wagon version of the Lamborghini LM002 for the Sultan of Brunei.
