I have noticed a whistling noise from somewhere at above 45 mph and finally managed to trace it to the windscreen. When you push on the base of the frame in the centre the noise stops! I recently had a whole new screen and frame fitted and the guy was very pleasant but admitted it was the first Caterham he'd done, so it was a bit of a learning exercise. It looks ok apart from a couple of creases but obviously isn't seating properly.
Before I start squirting sealant everywhere does anyone have any bright ideas?
