Environmental Leak-Rain and wash
Recently purchased my first Mercedes, an '82 240D with manual tranny, 211,00 miles. I love it more every day. After washing and waxing it the first time the rear right foot well was an inch deep in water. I removed the floor mats and mopped up the water. Two weeks later after a moderate rain the foot well was wet again. It is only the foot well and there are no signs of the door seal leaking. Any ideas?
