also most amazon SIDE COWL PANELS become badly rotted which will let water into the car and give you a wet floor it rots just where it mets the floor pans and carries on rotting until its repaired so carefully lift the carboard side panels out to expose that area and check just under the rubber mats and see how bad if thats the areas its letting in water
but fingers crossed you have caught it in time and its minner rot
