rented at Gibralta,La Linea, and although we booked insurance online on their site was told the insurance had nothing to do with them and would still have to pay the 1400(!) euro excess and would only be covered 3rd party,. Ended up having to pay their exorbitant insurance as well! although we gave our UK address all the forms we were given were in German and could not make any sense of the invoice. Fed up before we started our holiday!
