Nurburgring, glad I went but wouldn't go again, it got very expensive by the end of the week, 4 lap ticket was 80 euros 5 years ago. And the restaurant there is shit, crap food and rude staff. Nurburg's a ghost town by 9.00pm, stay in Adenau if you're going, I'd be tempted to camp next time. Actually I'd be tempted to head to southern France where the roads are amazing and free. D999 anyone?
