   [8] [9] This early attempt was an important step on the road to self-leveling, even if a full load would cause the whole car to lower evenly, rather than maintain height. In 1957, Cadillac introduced the Eldorado Brougham, a Rolls-Royce Silver Cloud competitor, featuring a new Air suspension with a self leveling feature.
