The 450SEL 6.9 was the top of the range, high performance version of the W116 S-class, produced between 1975 and 1981. To make it, Mercedes took an ordinary W116 and shoehorned the largest V8 into its engine bay that they could find: a mammoth 6.9 liter unit making 250 hp and 360 ft-lb of torque in US spec. They then added a sophisticated hydropneumatic self-levelling suspension system that gave these cars a dual personality. On ordinary roads they had a magic carpet-like ride that would soak up bumps in a manner entirely befitting a W116, while on the track they would handle far more nimbly and capably than their size would have led you to believe. The result was an early luxury super sedan; a 70s incarnation of today’s souped up AMG S-classes. But unlike their modern counterparts, on the outside the 6.9s didn’t look any different to the rest of the W116 lineup. Distinguished only by a discreet “6.9” badge on the trunk lid, the understated menace of these cars meant they quickly found favor among the sorts of people who wanted to go very fast and had lots of money, but didn’t always want you to know just how much money they had. Driven by Hollywood moguls, gangsters and foreign dictators alike, these cars were expensive, fast and technologically advanced.
Jumping forward to today, these cars have rather languished on the classic car market. You can still find tired examples on Craigslist costing only a few thousand dollars, often resting on their emergency bump stops as a result of failed suspension, with faded paint and sad interiors. Lately however, nice 6.9s appear to be climbing in value, with more and more nice condition examples coming to market with large price tags attached. And that leads me to today’s car.
