Just some info from an insider.
In Denmark we have just seen a small drop in registration tax for 2016.
Tax is 105 % on the value up to DKK 82.800 DKK and 150 % on the rest.
This is for cars up to 34 years of age. For classic cars from 35 years on it is calculated as tax of 40% of the base price from new.
Further on import
Outside the EU
Customs duties: 10%
Both customs duties and VAT are calculated based on the invoice price plus delivery and insurance costs.
In certain cases, for example when moving from one country to another, the vehicle can be imported free of customs duties or at a customs duties rate of less than 10%.
Within the EU
Import of used vehicle: No customs duties or VAT
Import of new vehicle: You need to pay 25% VAT.
