2011 diesel auto Opel insignia

Basically I’ve moved over to Dublin from Australia for a year and brought this car and didn’t understand the road tax as much as I should have. Had too stop driving it as it got too high. The car is an awesome drive and does really well on long distances. The key isn’t working because the battery has been dead for too long needs a jump start. And the key will be fine. Also the car will be good to drive as well. Never had any problems, few stratches and bumpes but noathing serious.
