The car was made in the EU so shouldn't attract import duty. Only VAT?
Cars imported into Ireland from anywhere, regardless of where they were made are subject to VRT (Vehicle registration tax). No one really knows how they figure out VRT, it could be based on moon phases', months of the year with an 'r' in them, how many pints the vrt clerk had the night before, or a figure plucked out of thin air. Any car over 30 years old regardless of value (10 million K Ferrari for example) is 250 Euro, however newer stuff is a minefield.
