The W140 S-Class launched in 1991 as the most overengineered car Mercedes had ever built.
Double-glazed windows to reduce cabin noise.
Soft-closing doors were the world's first on the W140.
A body structure so substantial the car weighed close to two tonnes before anyone sat in it; that is where the ''Tank'' nickname comes from.
For the first five years of its life, every diesel S-Class used the older OM603, a 3.5L unit carried over from the W126 that preceded it, still using two valves per cylinder.
In 1996, Mercedes replaced it.
The OM606.961 is a 3.0L turbocharged intercooled diesel with dual overhead camshafts and four valves per cylinder.
It produced 177 PS and 330 Nm.
The only visual clue that the car contained it was a TURBODIESEL label affixed to the boot lid.
0-100 km/h in 11.2 seconds in a full-size luxury saloon weighing over 1,900 kg.
Not a performance car by any means.
The most technically advanced diesel Mercedes had ever built, fitted to their most overbuilt car, announced by a badge you might have noticed because it's all uppercase.
A head porter in Kejetia was reportedly showered with various gifts after returning GH¢3,000 she had found to an information centre, which helped locate the owner and facilitate the return of the money.
