Walter, the door rubber seals are very similar to the Pagoda, and these have all been replaced in the past couple years. They seem to have the indentation you speak of.
The seals at the base of the window (top of door) have also been replaced, but they seem to have a large gap for water to seep into the door itself. As Ben points out, of more concern is the corresponding part of the rear quarter section, where the rear side windows emerge from the quarter section. I'd like to ensure that water entering this section drains out properly.
Ben, thanks for sharing a pic of yours-- awesome colour combo! As you can probebly tell, I've a thing for the colour green. My 230sl is moss metallic green (DB834), while the 250se coupe is dark green (DB268). Ironically, the original colour on the Pagoda was also dark green (DB268).
Thanks again for any information,
