Having looked at the 'long distance driving' comments it is apparent that the GT40 cabin gets rather hot and uncomfortable.Has anyone considered fitting a 'roof scoop' to force fresh air in right where it's needed.The sort of thing I mean is that thing you see on the roof of the McClaren F1 (though I think on the F1 it takes the air to the engine bay).I'm sure such a fitment could be made to look quite original.Anyone 'been there - done it"?
