My cousin wants to import a car to ireland, its a cosworth and on the V5 has no co2 rating. He said the duty depends on the co2 rating. I have no idea about this and so i have come to you learned folk on here. Are there anyways around it or model specds he could use etc.. to get the cost down.

 

try this Car Tax Rates in Ireland July Changes

thats for southern ireland but if its northern ireland its uk prices.

 

To be honest I don't think Cosworth will fit any of lower rates.
it's the most probably over 225g/km so I'd say your mate will hit the highest possible vrt rate :/
It's very annoying to be honest - so many nice cars, which if you would like to bring to Ireland are going to be too expensive with taxes...
