Has anyone experienced an air leak around the window? I have had my car in 8 times and they still can't seem to fix it - now the dealership is trying to adjust the window up - they have changed the top linkage twice, replaced the window molding, and the rubber cup holding the the driverside convertable top post as it rests on the body since it was not seating correctly. I really don't like my dealership ... any suggestions? Thanks!
