Hey I recently purchased a used 2007 Mazda 3 sedan (not sure trim level and only 99k) at a dealer auction thanks to a dealer friend the car was taken to the local mazda dealer to get serviced it had oil changed new brakes put on new tires etc ive had a lot of rain recently in my area and have come to discover water in the driver side cabin on the floor the carpet was and is soaked not sure what the problem is ive read up on possible door seal issues but im not sure only seems to be soaked on driver side was a little wet in the back driver side as well but mainly the front. Anyone have any ideas what would cause this?
