Im also wondering if someone got any information regarding:
B) BOVAG, whats BOVAG and does it qualify the dealer and/or the car in any way?
C) NAP, whats NAP and does it qualify the dealer and/or the car in any way?
BOVAG is a Dutch "quality sign" that means that the garage is member of a group of dealers following the rules of the BOVAG. If you are in trouble with the garage, much lawyers will only help you if the garagist is a member of the BOVAG. Also the BOVAG has rules about guarantees, like you can see in the advert: you can get 3 or 6 months guarantee. Especially for foreigners, it's sometimes more profitable to say: I don't need the BOVAG guarantee, because I will take the car to another country, and it's then more profitable to try to get something off te price.
NAP means Nationale Auto Pas. This system is introduced some years ago to give more insurance about the driven km's. If a garage is member of the NAP, it has to register the km's everytime the car is being serviced. With the NAP you can check at what km's something has been done with the car. If one of the earlier owners has brought the car to garagists that are not a member of the NAP or has done services by himself, you will find a gap in the km's. The system of course says nothing about the km's made before the car was imported, because it's only for the Netherlands. So the NAP doesn't really work for cars that have been imported or very old cars...
