It's a little hard to guage just what is included. To select a vehicle, I have to use year, make, model pulldowns. Then I get to see the top of a table of contents.
While spot checking, I saw that each year, back to 98, contains most info. Example: Body and interior section was included on 98's. Drop back one more year and the manuals have far fewer chapters. (no body and interior links)
The oldest year is 86. Only service bulletins are included for 86's.
Oh, did I mention the whole thing is like a web site instead of a book. It's not possible to page thru it. No index. No navigation bar. It does have a search function, but you have to know the right terms to put in or nothing is found.
It is very consistently layed out. The same series of links to takes you to the same info for each vehicle. If you know what you want, you can get to it quickly.
