Were those on open days like they still have? Some of that is kinda scary, particularly the guy showing off to his friends in the Beetle cabriolet (not a genuine Karmann Ghia one i hope!)
Other than that though, some nice classics there, though unsurprisingly maaaany BMWs, Beetles and 911s
A few other gems though, think I spotted an old Manta (or is 1970 too early?), Capri (Cologne!) and a few VW-Porsche 914s...saw one of those recently in metallic lime green...suprisingly larger and wider than I expected it to be.
Oh yeah (edit) can anyone place what part of the track that is?
