I got the dealer to check out my air con under warranty because I couldn't believe how useless it is at demisting thinking it must be out of gas or something , but to my amazement it was all okay , think I'm a bit spoilt because my work truck , an old disco 3 has heated screen ,but even taking that into account it's pretty rubbish , maybe it's due to how large but raked back the front screen is meaning the air hits the screen almost at 90 deg and doesn't flow well up it like on a more upright screen , other than that they are a lovely car ,could drive it around the world and not get tired ,although the turning circle does mean you could end up going around the world just to save turning around !
