Hi Klaus - I thought there was a European (German) version of the BBB published, or at least I seem to recall seeing them offered from time to time on German Ebay.
The term "BBB" (or Big Blue Book) has not been around for very long. In fact, according to my information, it was coined by a member here (David Pease from California) two or three years ago and 'stuck'. I have the BBB on CD-Rom as well as hardcopy, bought on Ebay for something like $90. I also got the technical data manual for my car from the Classic Center here in Germany. Depending on the year, it is available in English or German, or only German.
