It depends on which country you live in and which country the buyer will be registering the vehicle in. However, the buyer is responsible for finding out if this is possible.

The buyer will need to check with the relevant government department whether they can cross the border with the car or motorcycle. If it is possible, they'll also need to ask the local authorities about requirements (e.g. details about insurance, temporary plates and documentation).

The buyer will need to cover all costs related to pickup.
