We got back last week from a trip which was superb, we are already planning a trip for next year.
We got the ferry over from Rosyth to Zeebrudge, then followed the sat nav. We went over in 4 cars which after only 30mins got split up as the back two missed a sliproad. It which worked out better this way anyway as keeping four cars together in busy traffic was a bit of nightmare when you were the front car. The drive itself didn't take long on our trip through Germany there was a lot of roadworks and narrow lanes but unlike the UK the traffic still moved at a good rate.
We stayed in the Ringhaus hotel (
http://www.ringhaus.com/hotel_en/public/)which is two minutes from the enterance of the ring and it only cost us £140 ish for 5 nights so no point in paying for camping as folk we got talking too payed 48euors for 4 nights.
As alread said take a trip to Pistonklause in Nurburg (5minute walk from the Ringhaus) this place was packed but we had booked two nights well in advance of going, the fillet steak on a stone gets my recommendation ! Food and drink was very cheap we were having maybe 6 or 7 rounds of drinks and a 3 course meal for about 40 euros a night.
The ring itself is a petrolheads dream, plenting of expensive metal and when we were there at least a lot of UK cars. Its easy to get laps in other cars like GT3s, M3s/5s etc and the like, the universal point at the passanger seat works a treat. At the weekend we hit the track at opening time and it was dead you could do a lap without seeing another bike/car. Just make sure that when you are going the track is open to the public as it isn't always.
I personally took it pretty easy round the track and treated it like a fast A road I didn't know. Some people however were pushing very hard and generally these were the ones that hit the barrier a UK Mini went past me sideways with a 130mph on my speedo two corners later he had clipped the barrier. A S2000 spun and cracked hit back bumper however he had to pay £800 for a little dent in the barrier. There is constant reminders with totally wrecked Evos/BMWs/Porches getting taken off the track but all of us drove at 90% and didn't have a problem.
You can easily rent a ring track car from the likes of Mk5 GTis, R32s, M3s , Porche GT3S, Megane F1 R26 all of them had cages but otherwise looked like standard cars. The Megane/MK5 GTI was 575 euros for the day.
