inventory selection

Hi,

I'm trying to create a new content type named "Inventory" where I can select from a Taxonomy list of vehicle manufactures.
For each of these manufactures they have their respectful models associated to them.

How can I use this module to only display specific models of a selected manufacture?

ex: if I select a manufacture from a drop-down menu: Volkswagen I will then see my Models field display: Beetle, Golf, Jetta, Rabbit, etc

Is this possible with this module? or do I have to create a field for each manufacture?

thanks
