I'd like a recommendation as to what books to buy for me to be
able to work on my 2000 Sonata.

I'm not going to rebuild my own engine -- no work of that type.
But I want to be able to do routine repairs and a mod here and
there to my electricals, door components, etc. I want to know how
the radio is connected to everything, where every relay and fuse
is located, and especially how to replace that lightbulb that's
out behind the heat control knob -- which panels have to be
removed to get to it and where the fasteners are located. Whether
a task is to be done by me or a professional mechanic, I want to
know what's involved.

The Hyundai parts manager quoted me $45 for the shop manual,
Volume 1. Volume 2 is $18 (electrical). He said that this is the
literature that they use themselves. I assume that these are the
same books that Helm is selling on their web site.

Another party offered to sell me the manual on CD for $165 (Helm
does not list this one).
Do these manuals cover the vehicle adequately, or do I need to
buy a "parts catalog" in order to get decent diagrams?

My experience with aftermarket books in recent years has not been
good, and they seem to be getting worse. These publications seem
schizophrenic, leaving out a lot of routine repairs and even
omitting some routine maintenance, but concentrating in intricate
detail on rebuilding every engine that was ever used in the
model. My purchase of Alldata/Popular Mechanics CD ROMs was even
worse; the disks contained very few diagrams, and all diagrams
and charts were rendered with such terrible resolution as to be
virtually worthless.

Advice?
