In the last  two years we have been asked questions, twice while out fishing, (with fishing licences). The first time they asked if we lived in the village where we were fishing. We said No, but if we had of done they would have known we were telling lies because they had already checked the Spanish car. Yesterday I read an article stating that not only are U.K. plated vans illegal here, but totally illegal to have any sign writing on them also. So beware! So what is the difference between illegal and totally illegal ??

If paying cash to the Mossos for a Multa, E50 or E100 iirc.
