I use a Europe Wide Breakdown Policy supplied as an extra to my Morgan car insurance (through Gott and Wynne in Llandudno). If memory serves me correctly the premium was less than £30 (and of course it only covers the Morgan). Not sure if you can take it out in isolation or if it has to be taken out with your annual insurance. Worth a check with G&W though. Although I have yet to use my cover in anger, I seem to remember speaking with a chap at Devamog who had the same policy and had been successfully recovered from Italy to UK (he was not happy about breaking down in the first place of course, but nice to know that the car will get home safely and one less thing to worry about).
