Found a wagon on ebay - appears to be pretty good shape, but headrests are missing on rear seat. Initial comeback from seller (a non-MB dealer) is that these were optional.

I have never seen one of this vintage without them - looks like there is likely even a safety issue without them as the seat backs are thinner than in years past and the plastic supports for the headrests would probably cause head damage ... any chance these were "optional" - I figured the first owner was the type that didn't like the visibility issues and removed them all - hopefully never carrying another in the back seat!

Thanks!
