Come on, of course I was exaggerating with the reference to part numbers but even the time of the parts guy isn't for free, one may do it with the intention to show good service, and expect a customer come next time. I would prefer the parts guy serve me instead of using his time for free for someone else. If he had nothing else to do, why not give it for free then but nobody can assume they should do it.
Considering the Russian site, it does not have any single detail more than the MB files, after all, it is stolen MB data (I cannot afford being that picky, I'm using and referring it often). But try a print from that site for a document to register a car, I would like to see the face of the officer. Even if DansSlk was so polite to print the data card, even his printout would not be sufficient.
People complain elsewhere MB shop prices, that is justified to me but not any more if you expect them do an official proof of car origin for free.
Note, I did not consider the VIN and data card info any secret (I've said it before, but I've also said I would not post VINs of my cars), I'm not complaining someone giving out that info, I just don't accept the view that that one can expect getting the info for free.
