If your car develops a problem at the 'Ring, there are a few garages in the area that can help. Many of them are used to seeing high performance cars, and receiving foreign customers. Some of my favourites are listed below. If you have experience of a garage that should be added to the list, please send me an email with the details or post it in the forum.
This is a small independent garage in Adenau. I have used them for brake pad and wheel bearing replacement but they can do most repairs. They have two car lifts but I didn't see a bike stand. Nico Lieder owns the place and although he doesn't speak English, two younger members of his staff do. Both occasions I used them I didn't have to book a time to come in and the work was done quickly and I was pleasantly surprised at the low cost.
Address: Haupstrasse 207, 53518 Adenau (on the left as you head from Adenau to the Nurburgring)

Race car preparation
Many German race teams are based near the Nurburgring. Most of these also offer track car preparation services as well such as rebuilding engines, suspension upgrades, bodywork repair or replacement, and installing roll cages etc, all the way up to full racecar preparation or restoration. In addition, many teams and garages will often let you store a car and wheels/tyres there for a fee, so you can travel to the 'Ring your car is ready to go when you want it.
