Hi, I bought a coupe last September and later noticed a swimming pool under the carpets both sides. Left it until last week to look into. Seats out and side trims off, carpet lifted as much as possible and left the doors open for a week in the sun. The carpets and floor dried out completely so put back down. Next day went to put seats back only to find floors wet again. No rain, only hot sun, car under SORN so not moved, this must be condensation between cold metal floor and foam under carpet. Anyone else got this issue? Going to try a waterproof membrane but this seems strange.
