What can you guys tell me about this amazing race? I can't believe I haven't seen a story about this marathon on Motorsport magazine or anything. I know the race ran from 67 to 70 and combined the 28 kilometres of the Nord and Südschleife of the Nurburgring. The race was run by production cars (MGB, 911, 914, Volvos, etc).
Why did it stop and what is the story behind it? Man, I can't believe they held such an event......
