a question about repair manual

i'm considering to buy a general repair manual for my 01 GTP. I checked on ebay, some sellers sell "Haynes Repair Manual" and say that this manual covers 00 01 02 03 Pontiac Grand Prix and they post a picture of the manual. But when i enlarge the picture i found that the cover of this manual says it covers GP from 1988 to 1999. should i buy this manual?
here is the url:

Haynes is not a very detailed manual but is adequate for the diy'er. You can pick them up at any auto parts store like Autozone.

If you want the mac daddy of manuals..go with a GM shop manual. You can sometimes find them on Ebay.

Here's a link to order a new one.
