When I got the car almost 2 months ago I gave the car a good check over for damp and checked in all the normal places. The wether had been crap so lots of rain, all was fine with the car checked it a few time since and still fine. a few weeks ago a place a few tools in the drivers side floor bin (still dry) pulled them out yesterday and they where damp. The floor of the bin feels a little wet. Now the problem is it's not rained where I live for over a week. So where as the water come from? also how long do they hold water?
