Not the only insurance black hole for NI folk. I used to rent cars from branches of Enterprise in Belfast quite a bit, and although they were able to delete the rental clause that forbade taking the car "outside of the United Kingdom" they hadn't been able to extend breakdown coverage. So their advice, if you broke down or were involved in an accident south of the border, was to have the car towed or carried to the border, and then they'd be able to dispatch their own recovery contractors
