Is it normal for the m3 doors to have a pretty noticeable rattle upon close? (They don’t have a persistent rattle *after* they’ve been closed, it’s just a single rattling noise the moment they’re closed). I’m thinking it’s due to the frameless windows, but I’m not positive. It might be normal for cars with frameless windows. It’s really not a huge annoyance, more just something I’ve wondered since I got the car.
