In 1969, Yamaguchi launched the 417, a very simple sedan for a low price.
But they lacked a top model for the brand, and the Italian sports car company Cavaliere Nobile did not have an entry model.
Both teamed up, and the Italians increased the power from 72 to 91 horsepower while giving the coupe a sport suspension, a five-gear transmission right out of their sports cars and a really expensive interior.
This is definitely the most exclusive way to drive a Yamaguchi. After two years, in 1971, it was presented with the Cavaliere being the fancier one, while Yamaguchi sold it with a four-speed, a less fancy interior and slightly more comfortable suspension.
The car was not a top-seller, but overall sold with pleasant revenues. This was one of the very first cooperations between the Japanese and a traditional brand from Europe.
