I have the same complaint about the roof rail seals. That darn upper rear corner. I can roll the windows up with the door shut but that corner makes it almost impossible to not have an air leak there. As with the door seals, I guess it's better than nothing. The original roof rail seals on my car were only there for looks. They were basically petrified. The door seals weren't a whole lot better and that's when the car was only 8 years old with no evidence it sat out in the sun excessively (the dash pad and top of the rear seat were like new yet). I have a feeling the originals weren't exactly made from the finest materials, lol.
