I must admit I prefer a nice crisp dry winter run in the Aero , with the heater off everything is nice and toasty.At mog 18 this year we had the aercon on for the three days but it blows in above your feet my left foot swelled up quite badly.I have thought of louvres but dont fancy the water ingress. The trouble is as soon as you stop the whole front end becomes one big heat soak.
