Hi,
Couple of pieces of advice. Any sign of excess moisture underneath (how are the front fog lights looking? Fixtures rusted?)? Would suggest you get the oil cooler pipe at the bottom of the rad replaced/ checked out. You don't want this pipe failing as it'll start all sorts of problems with overheating and head gasket issues.
In relation to the wind noise, I got hold of some tubular piping (can't remember the width though). Pulled back the rubber around the front door frames and slotted the piping into a little gap that's within there. You can't go too thick with the piping as the rubber will protrude too much and stop your window from going all the way up. Too small a thickness and it'll not be effective. Get the width right (and I did trial and error) and the rubber will be pushed out just enough to create a better seal. Didn't fix the problem 100% but it's wayyyy better than it was. The plastic gusset (by wing mirror) has split just at the top on mine and I think that's where most of the wind noise is now coming from.
Steve.
