Wind Noise really gets to me too, its so loud, i need to drown it out with the radio.
i think its just simple arodynamics that are missing, for instance, i noticed that on the rear passenger doors, there is a little dip in the flushness of the lines from the end of the door and the rear pillars, about half and inch "step".
Would wind deflectors help with this?
I was thinking the same thing, was checking out ebay for wind visors, they aren not expensive. But it sounds like the doors are not well isolated too.
