I've always preferred Chilton's to Haynes on my other cars, but they're about the same in terms of what they cover. For my Crown Victoria, I picked up a Haynes at 1/2 Price Books really cheap.
For our New Beetle Convertible, I "bit the bullet" and paid for a brand new Bentley manual. I chose the actual book rather than the CD/DVD version because I'm not comfortable having a laptop in the garage when I'm working on cars.
