2003 Mercedes Benz E500

Interior problem
2003 Mercedes Benz E500 V8 All Wheel Drive Automatic 90000 miles

I have a 2003 Mercedes E500 Sport. A couple of months ago I noticed that the front drivers side floor was soaking wet and I didn't know why. I thought that it may have been because of rain, but I don't think that is the problem because the floor gets wet even when it doesn't rain. Now, I have noticed that the same thing is happening to the floor in the back seat on the drivers side. Many times when I get in my car, I check to see if the floors are wet and they are and I can't figure out why? Please help!
