Peeps, I have been reading your thread with interest the past week as I took delivery of a 4500mile ex-demo 2.0tdi se copa on Friday.
Saturday was a good day for misting-up, but it would have been in any car. Dropping the windows a crack is the usual way I would deal with misting. The
problem with the Altea being that there is no overlap of door frame at the top of a slightly dropped window to allow air in but deflect a lot of the rain streaming down off the roof.
I lived several years in the Balkans where we had Med temperatures in the summer but often had mountain storms blow-up at any time. Therefore I, like many others, fitted wind deflectors at the top of my windows to give adequate ventilation in the heat and prevent misting, yet deflect the rain.
This is the way to go I feel with my Altea. I have seen a mention of them in an old thread here, but having reviewed some adverts pulled-up via Google I cannot determine if - due to the chamfered window seal - these deflectors use double sided spongy tape to fit on the door, or if indeed they manage to fit up in the channel above and behind the seal.
So I wonder if you have thought of deflectors, and also if anyone can recommend a make that does not 'stick on'. TIA
