I am working out what Taxonomy to use with our Drupal Content Managment system approach.

The taxonomy is the outline for the site, and the classifications that help users to navigate the site. Defining a clear taxonomy helps users read the site, and find the information they are looking for.

The main website is organized right now into Forum, How-To, Year by Year articles, Videos, Links, Info from Bruce's Cars, and article highlights.

The new taxonomy might be :

How-to / Repairs
-Modifications
-Repairs
--Body
--Electronics
--Powertrain
---Engine
---Transmission
... more

Specifications
-Year to year changes
-Specification details

Car Models
-Deville / DTS
-Seville / STS / SLS / STS-V
-Eldorado / ETC / ESC
-CTS / CTS-V
-Escalade / EXT
-XLR / XLR-V
-SRX

So that if a user navigated Escalade -> Repairs then they would arrive at articles that cross-referenced both items.
