About the Mercedes-Benz S-Class W140
The W140-generation S-Class is widely regarded as the last Mercedes-Benz engineered to a standard rather than a price, famously costing the company over $1 billion in development. The S 600 sits at the top of the range, featuring the M120 V12 engine that would later find fame in the Pagani Zonda. It introduced numerous innovations to the segment, including double-pane soundproof glass, soft-close doors, and the first production Electronic Stability Program (ESP). Despite its massive proportions, the S 600 offers a remarkably serene and effortless driving experience, earning it a reputation as the ultimate '90s 'Diplomat's Express'.
