It was obvious to me and it doesn't matter for the thread but there are still a couple posts that seem to leave it out.
But alas we still had to figure out how you had a euro car.
S is not the common US term for wagons. We use T-124.
However if you read this,
http://en.wikipedia.org/wiki/Mercedes-Benz_W124
It DOES reference the Wagon 300TE as the S124. If you google S124 you get pictures of wagons. Google T124 and you get nothing.
In terms of chassis designation my belief is "S" is the correct designation on a wagon. However in terms of bootlid badging, the T is the letter used for wagons.
300TE, 300TD, 250TD etc.
In America people are awfully proud of the turbo on their cars so they like to kick the "T" into the name of their car even though the T doesn't correspond to the chassis, or the model name.
Maybe these help
