You are probably already aware of it and im not sure if it applies to Swiss made cars but it may be worth mentioning anyway, atleast on US built export cars there are atleast two different speedometers available, 200Km/h and 240Km/h, my 73 Duster built for export in the US has the 240km/h speedo,but i have seen and own an extra 200km/speedo aswell the later version seems to be a whole lot more comon.
