ADAC? That’s correct. ADAC is the German Autobahn’s super roadside service entity, that responds with special equipment that are self contained and can literally repair your car on the spot right where you break down on the Autobahn. Their drivers are welders, mechanics and a parts house and fabrication shop.
This is the state of the art in roadside service in the world, as far as I know. Try using Google’s Language Tools to help as this site is completely in German, for obvious reasons. Awesome and something to behold, even it’s on the Interent.
