Be smart! The Swiss vignette is easy removable if you stick it on to a transparent adhesive vinyl. First, let's not forget, the vignette is printed and it has its sticky side, in order to put it on the inside of your windscreen. So, you cut a neat piece of transparent vinyl, just a little larger than the vignette, and you stick that on the inside of your windscreen. Than you stick the vignette on the vinyl! Done! Later, if you are travelling to Switzerland again, but with a different car, you remove actually the vinyl (with vignette sticked on it) from the windsreen. Just ordinary transparent vinyl is fine. (not too sticky!) I have been travelling non stop to and through Switzerland, with different cars, for holiday and business purposes. I have saved quite some money by doing the vinyl trick. You buy maximum (and minimum ) 1 vignette per year, and like that, you can use it and remove it as many times as you like, during that year. If you don't need it for some time or for the remaining months of the year, you can sell it or give it to someone you like.
