I was exactly the same, until I went!
To be honest, driving the 'ring doesn't really bother me, as it can be a very dangerous place (My first ever time out I saw a huge 8 car pile up, with some very badly hurt people
)
The thing that got me though was the atmosphere of the whole town of Nurburg. It's a true petrol heads paradise, that you can't explain until you've experienced it. The first time I went, we were in the petrol station down the road from the 'ring, cleaning the cars, and while we were there about 10 different Ferraris came and filled up with fuel, from all over Europe. Now that's not something you see every day at your local Shell garage
