The CD is really good for that reason. YOu can print, ruin and throw away and have a sheet at a time on your engine or wherever. You can blow it up really large to see detail if you have to also. I have a Haynes coming to me via ebay to supplement what I already have. Tons of info on the CD once you get used to it. Between the CD and these internet Mercedes lists and Bulletin boards you kind of have it all. The info here and the other mailing list is first class and is really the way I have become aware of all I know about the cars.
