Got the 2004 paper manual last night.
So far, it seems that the cd's and paper manual cover all the same things. Each has its positive aspects.
Paper:
- Easier to read
- The diagrams are legable. In the cd's I have to constantly zoom and pan around.
- I can leaf thru the pages. Eventually I see everything.
- I tend to notice all kinds of stuff as I look for specific items.
- Table of contents
- Index
CD:
- GM's entire product line is included. It's a very cost effective way to get info on a lot of cars.
- It uses links to let you jump to relevant procedures. Like how to get the dash off before removing the radio. This is a case where flipping thru the pages is a draw back.
- You can print what you need and not worry about getting the pages greasy.
- Cut and past works better than with paper

Great for email.
- You get a web server installed. There must be a way to use that for more than just the service manual.
- Full text searching
All in all, I'll recommend paper over cd's. Unless you need to see info on the entire GM lineup.
