I have to leave my 2002 convertible C5 outside, but it's always covered with a rain and /or heavy breathable dust cover. Recently after some rainy days both the driver and passenger floor rugs were soaked. Where could the water be getting in? I do not recall how far down the top went on the sides over the windows. Could it be the top has shrunk?
