I spent some time this weekend washing the Boxster. After I was done I noticed that the driver side carpet was wet, and when I moved the car for the first time, some water dripped on top of my foot..

I didn't feel any water on the passenger side, or under / behind the seats.
Car stats are: 2000 986s with 64K on the clock.
Has anyone else had this problem, and what was the solution?
Thanks,
Eric
