We like real air too, our car comes equipped free of charge with opening glass windows in each door. You can see out of them and they are great for seeing where you're going! (which a sunroof isn't)
All the benefits, but £1000 cheaper!
Except the roof-rack inspection view, which is a good one I suppose.....but when the bikes fly off you'll still see them get run over by that 40 tonne truck in your rear view mirror!!
