The rhetoric from the Gov and Irish motors dealers seems to be the UK is dumping its 'unwanted imports' on us...and we must charge our own consumers to discourage this awful practice and stop it immediately for the good our children.
The cynic in me sees it more as a way of restricting the selection the Irish consumer has by cutting off the UK, thus driving us into the arms of car dealers in Ireland, where VRT is a greater take for the Gov. Win/win for everyone except the consumer as we will be forced to fork out for new cars when there is ample used selection out there that would more than do the job.
The price of cars in Ireland, along with their basic specification, means the Irish consumer is shopping abroad for a better product.
UK cars are ending up in Ireland because the Irish consumer wants to buy them, due to the better price and spec they offer...not because the UK has a strategy to use Ireland as a breakers yard!
