Hi guys.. I'm new here and been following this thread for a while.. took the plunge and got an F30 and guess what.. wind noise was an addition to the car!
Took it back to the dealer. .One guy confirmed the issue and took it in and adjusted the doors and explained its fixed. Got it back and it wasn't. Another guy mentioned exactly the same thin glass talk but I'm not 100 % buying it as there doesn't seem to be many complaints about it and lots of reviews say its a quiet car!
One thing I noticed is that when you sit inside there seem to be a space between the door interior and the body of the car.. anyone noticed this? I can see the body of the car from that space.. not sure if it is the reason.. but the plan is to take the car back and see
