Count another vote against aftermarket window seals. I installed aftermarket A pillar seals and they were a constant nightmare. I finally went to my local dealer and paid the money for the MB seals. The original MB seals are much softer, hollow, and conform perfectly to the window and A pillar. As soon as they were replaced my door problems disappeared.

If you're replacing them yourself, be aware that getting the A pillar seal and the hard/soft wop window seal to line up properly is a little bit of a hassle. I had to tweak them a couple of time before I got them to line up so there was no wind noise or trouble. You can install the front around the chrome strip, but don't glue down the window side of it until you're sure you've got it lined up right.
