Does anyone has or know where I can get a cargo retainer? It fits on the trunk/boot of a w123! It allows you to carry large objects because it locks the trunk lid in-place!

I'm not sure what you are talking about. Are you talking about a luggage rack that goes on top of the trunk lid?

I suspect he's talking about the 'rods' that allow the tailgate to remain PARTIALLY open to carry long items, but prevent the gate from bouncing to the full open position. I've seen such things in use, but I've never seen any OEM solution to this problem.

Interesting. Never heard of such a thing.

Thanks, you are correct; it is the rod that attaches to the trunk to hold it in place when carrying large objects. Note: like a bungee cord , but solid.
