Opel Kadett Cabrio by Erhard Schnell (1966)
Since when do Belgians read German Oldtimer magazines? 
How big is the chance that you pick a picture from the only 'Auto Bild Klassik' that I own? (A colleague gave the magazine to me when he finished reading it).
BTW: Judging by the article about Rainer Schlegelmilch in the same magazine, I'm looking forward to the his book that should be published soon!
