Netherlands:
No, if you have a car in the Netherlands Allianz decides that the damage occurred to your car is covered, they will pay a ‘Tophersteller’ to repair the car directly. A Tophersteller is a car repair shop approved by Allianz. A list of Tophersteller can be found here. Allianz will not pay out to a garage not considered a Tophersteller or an owner directly.
Sweden:
If you are renting out a car in Sweden you may only repair your car at a workshop approved by If. Most are though, so simply call and ask If you preferred garage is connected.
