Water leak

: I have developed a water leak on the passenger's side of my 1980 300D. It collects on the floor inside near the front of the seat. I have checked the body drain and the drain under the hood. Are there any other areas to check?<p>Jerry-<br>Make sure you checked all 4 under hood drains (1 in each hinge area right and left, and between firewall and fenderwell right and left). Also, if you have a sunroof, check the sunroof drains. Lastly, is your rear windscreen rubber seal factory, or a replacement? Non-factory seals are notorious for leaking. Even factory seals have a compound that can dryout and leak over time. The rear windscreen leaking is not likely the problem based upon where your water is collecting (unless you have parked nosedown on a steep hill.) Hope this helps. -SR
