Hello,
I had a thought the other day whilst dodging thunderstorms with the roof up. Would it be sacreligious to fit a small vent in my front windows ? Something like this :

They work really well in small aircraft and I can't see a reason not to do it. I'd like a bit more cold air when it might rain. Also, 4 seater so the roof takes a moment !

Thanks,

Marc
