The printed manuals are getting rare, and are not cheap. You need a full set (engine, chassis+body, electrical, and climate control). That auction is for the engine manual only. I bet it could end up selling for $50-$100. The CD manual is available from your local dealership for about $100, but some of the PDF scans can be poor, depending on the chassis & manual. I have both the printed manuals and the CD, as well as the WIS.

You can also get a 'bootleg' copy from various sources, including eBay. Drop me a line if you want more info, or if you want a copy of the EPC (dealer parts catalog).
