Mold smell

As mentioned few days ago, rusted plate was found under the room air-conditioning system. I thought the harmful water had come from the physical thermal interrelations by conditioning, but the rain fall and the naked place showed the origin of rusting water did from the roof leak on rear window shield rubber portions.
Additionally some mold growth were found under the needle fuerte insulator, the strange smell must have come from the mold growing in invisible places in the cabin.
In order to eliminate the old strange smell, the inner layer of the cabin in addition to the carpets must be replaced to restore the automobile perfectly.
Though I'm interested in the mechanical restoring, not so much in outer painting nor interior augmentations.
I'm satisfied about the software to the level at not giving discomfort to the others, because I would deny any meaningless decorations on the automobiles.
