Very nice.
My brother and I were there last July for his 1M. (Noticed the black 1M in your avatar)
We were able to get into Mobile Tradition which was a dream. However, unable to get to tour the M-plant.
What are your stops? We went right to Munich to the Nurburgring and back.
I'm "repaying" him with my PCD on the 22nd. We are flying into SC, renting a car, driving to Petit LeMans; then picking my X1 up.
