We needed to use ADAC for our car at home, I was concerned having read many negative reviews. This was my experience. Telephoned ADAC (you need to push '2' for 'breakdown' once the machine answers) immediately put through to a polite English speaking person. Five minutes later received text from AA confirming they hope to be there in 35 mins, followed by another text confirming they would be there in 15 mins and arrived within 5 mins! So from our telephone call to Germany the ADAC / AA was at our house in 20 minutes. He also helped with some advice regarding our van.
