Need to wait until they release the tourist schedule for the track. If you look now it shows which days track is open for tourist drives, they release it around march time for the season ahead. Anytime would be good around now. Just need to link it with Alex's school holidays.
My main car is a Skoda Octavia vrs, Skoda used to have a less than desirable reputation, but it's owned by VW now, so it's basically a golf GTi.
Adenau is basically on the track, so it's great, accommodation is cheap. Sure we could pick you up from an airport.
