Project Benz documents Mercedes S-Class (W140) culture without softening it: the cost-no-object flagship with double-glazed glass, the M120 V12 in the 600SEL and S600, the V8 500SEL, the durable straight-sixes, and the diesels that anchor the daily-driver end. It is part owners' registry, part technical archive, with factory specs for every W140 variant, restoration and buyer's guides, paint codes, and wheel fitment, mapped to real cars in real garages worldwide. The cleanest Mercedes W140 builds and the reference to make sense of them, on one feed.
The W140 is the S-Class built with no expense spared, the car often called the last over-engineered Mercedes. Large, heavy and immensely solid, it introduced double-glazed glass, a V12 flagship and a level of construction the company stepped back from afterwards.
The 600SEL and S600 brought the M120 V12; the diesels and straight-sixes are the durable daily choice. Values have turned, and clean W140s are climbing as the model is reappraised.
No W140 builds in the registry yet. If you own one, it belongs here.
File the first W140 →Document your car, put it on the map, and help build the S-Class section. Any state, stock to modified.
