Yeah, I bought this VADIS DVD from this seller. All in all pretty useless. I was expecting lots of pics for repair info and instead this includes lots of poor drawings. I think this info is really intended for an experienced mechaic vice a do-it-yourselfer. Save yourself the money.
I can't say I've been disappointed. I have the original paper manual for my '71 1800 E, the '96 850, and the VADIS manual has almost the same drawings, etc. I'd say it is the best of a worse lot. Haynes and Clymer are even worse, fro what I've seen. And, you get parts listings.
