My car sits on an incline in the driveway, and I noticed that when it rains, the right rocker fills with water. When I pull out of the driveway and get the car level again, I would guess a good 1 or 2 quarts of water drains from the drain in the picture. Its the drain located below the right front door. The left side never does this. Is there a drain toward the rear that might be clogged on the right side, not letting the rocker drain when it is on an incline? How does water get in the rocker? Clearly MB intended water to get in there, why else would they put drains? But I don't like the fact that water is sitting in there causing rust no doubt.

I believe that is the sunroof drain.
Find out why your other side doesn't flow.

No, that is not the sunroof drain- the drains are on the A and C pillars.
The rockers were not designed to get wet, but they did get drains in the event they do get wet.
