Has anyone experience of this? I have been offered one but would need to register it here. I wonder if there are any pitfalls.
You need to have owned the vehicle for six months to avoid import taxes, so that's something to bear in mind if you're acquiring it from someone else. The info you need is on this site:-
Having said that, the VAT and the "green" tax shouldn't be much, as its based on the new price of the car and goes down depending on age, so an old car shouldn't attract much tax.
