When I was buying my X, I drove 4 different ones that morning. It was a pretty windy day and the first one right away had wind noise coming in around the doors. So did another one, and two of them were quiet.
I bought one of those that didn't have the noise. Seems like their door seals and upper window frame ridgidity have some issues, as in a very strong side wind, you will still get some noise from the downwind door.
