For over five decades, the Mercedes-Benz S-Class has carried a heavy burden: the self-appointed title of “the best car in the world.” As an industry veteran who has spent ten years analyzing automotive depreciation curves, lease structures, and the granular shifts in the luxury market, I’ve seen contenders come and go.
