One of our members got crashed into in his Porsche Carrera with no fault of his own and got no help from the German police but that's another story, it's an expensive result of being in the wrong place at the wrong time.
And that, unfortunately, is the reason why I doubt I'll ever drive my own car on the 'Ring
I'm confident in my own ability and self-control not to go mental and crash: I'd just treat it as a road and drive accordingly. But to get driven into and have your car damaged through no fault of your own... that sucks. Hope it gets sorted out for your mate.
