Yea, went in 2002, It is grate, they changed the order of the stages last year. but yes they take Euro's in germany, dont know about Lux. Greate place for rally, stay in Treir really cool "OLD TOWN" (something like 2000 years) If you go to any of the Baumholder stages, you must goto the "GINA CREST" It is a killer jump, Rent a car because you will need it the stages are all like a 1/2 hour from Treir, plus if you have not driven in Germany you owe it to yourself
also be prepared to drink a lot of cheap but good (like 1 euro a bottle) German Beer, and eat a lot of Vistverst (killer german sausage) Beer trucks and Sausage venders are everywhere
All and All I hade a blast at the Rally Deutschland and I'm sure you will to. p.s. If you like F-1 SPA and Nurbergring arnt very far from Treir.
