with such a “sauwetter” as yesterday (from Cologne 600 KM towards the south) must basically stop all 50 or 100 KM, to clean the side windows (front) and the outside mirrors, because nothing else can be seen. They are so dirty within a short time that they can no longer be used. At least that is not “upper class”. This can be much better even my former first and present second car X3. There is nothing dirty there. Even my wife’s car (Chevi HHR) can keep the side window and mirror clean with even so strong “sauwetter” without any problems. Greeting Jürgen
