Some good reading to find out everything you about the Classic VW:
"How to keep your Volkswagen Alive" By John Muir
Interesting and humorous reading by one of the earliest VW enthusiasts. Some of his findings and techniques are dated and we've learned alot since then, but it will give you the basics, and knowledge to keep the Bug running in almost any situation.
Various catalogs:
Rocky Mountain Motorworks/Real Source
California Pacific/JBugs
California Import Parts
Wolfsburg West
Most of the above send out their catalog free, or give the catalog cost as a credit on the first order. Looking through these will give you an idea of what's available in replacement parts and how much they cost, so you can get an idea of what it would take to bring an ugly Bug back to being a thing of beauty.
Welcome to the addiction.
