In Europe (not only in the Netherlands) Mercedes provided, during a couple of years (I think "89 till "94) some of their models (like the W124 and the R129) with two different types of 3 liter engines.
The customer could choose for a 300-12 valve engine (like in the W107, early W124, and W126...)
or a 300-24 valve engine (which obvious was standard in the US).
Some of the MB owners (especially Dutch ones) think it is necessary to let the world know that they spend more money on their car by getting the 24 valve engine instead of the 12 valve engine. Just to show those extra costs, they have the (original MB) badge 300CE-24 stuck on their car...
Germans do not brag that much about their car and drive non-badged cars (mostly).
