Mercury Cougar allows water to leak into areas that should be kept dry: driver's seat, passenger's seat, & especially hatch area. 'Had to throw out multiple carpets and deal with stench of mildew. 'Able to see where water enters into hatch (through a spot welded seem near tail-lights) but solid sheet metal is above this area; multiple dealerships have been unable to diagnose how it gets in. Source is definitely not the rubber seals around the tail-light or hatch; these are tight. Only other source might be rubber gutter seals above windows, but there is no way to know unless they are removed. Problem is they can't be replaced. New ones must be purchased, custom painted, & installed.
Selling it; buy Japanese or German. They might not know how to win wars, but they certainly know how to build solid cars.
Mercury should take up its responsibility and have these parts replaced as a recall. Since it is not a life-threatening safety issue, they won't bother. They will just have their customers deal with the inconvenience of having water-soaked carpet and the stench of mildew in their vehicles.
