In 1956, King Ibn Saud, founder of modern Saudi Arabia, commissioned Carrozzeria Ghia (coachbuilders) to make two identical cars for him. One was a 4-door sedan, and the other was a 4-door convertible.

Barring the front grille and the engine of the W186, the entire Mercedes-Benz car was revamped. His car had powerful air-conditioning, a telephone, a foot-board for bodyguards that could be pulled out, etc.
