I can remember shopping for this car when they were new. These look like the original thing to me.

And I remember these rather clearly since it seemed Mercedes was just trying to hold on to former customers who expected such things. After all, this was the norm for Mercedes from the earlier times and Rolls-Royce still had them, so customers expected them in this price class.

The big deal was 'No paint shall show through on the door frame or door interior'.

And oddly enough these also acted as sound insulation and not just trim.
