Nurburgring - Good Riving Roads...(Black Forest??)

[snozzberry]

I'm planning a little road trip with me and a mate in 2 seperate cars. We're going to head over to the 'ring from Calais but then we want to find some decent roads after that, nice scenery would be good too.

Don't want to go as far down as Stelvio etc. trying to keep the whole trip well under 2,000 miles. Are there any good roads in the Black Forest or around Germany and which would be the best route to take back to Calais.

I guess the limit South is about Zurich area, is that far enough for some decent driving roads?

And what would be the best way there/back?

Thanks a lot!

Also, what are the petrol prices like in Germany, Belgium and Switzerland etc. where will be the cheapest to fill up and is V-Power readily available all across Europe?
