In all European countries the license plate has to match the country where one is resident. In some countries the taxes are high and car makers try to compensate by lowering their prices. To still make it affordable to buy cars. Like for Denmark and Netherlands. For residents from other countries it might therefore be worth it to buy a car there and then export to their own country.
