Hi guys, my first post here and I need your advice (obviously on a Mazda CX-3). It is a second-hand import car and the dealer says there is no known damage history. This ‘paint damage’ is present at the rear of the car. In addition to the fact that the bottom comes loose and moisture comes in, you can also see a dark smudge above it. See the photos below. Does anyone have any idea what happened to this car (repainted? damage?) and how this piece is able to come off?
