I am Irish so I know all about tax in the emerald Isle, its why people have moved to tractors in the hundreds of thousands in the last 10 years for cheap tax. (low C02 apparently!)
Tax on a 250 is crazy let alone a 5 litre ISF.
My ex worked in Singapore, you can't own a car there unless you are uber rich, forget about any new ish Lexus of any kind unless you have money to blow, loads of money.
