 Mercedes-Benz strengthened its position as one of the world's most desirable brands of car by introducing an all-new version of the acclaimed S-Class luxury saloon.The range-topper of the new S-Class range was the 560SEL, which was powered by a 5.5 L V8 petrol engine and had a top speed of approximately 150 mph, making it one of the fastest four-door cars made up to that time.After almost a decade on sale in Europe, Fiat exported the X1/9 sports car to America.
