I would like to add many new categories for our global automotive forum. I would like to separate the different car models for each country. For example:

USA
- model 1
- model 2
- model 3
United Kingdom
- model 1
- model 2
- model 3
Germany
- model 1
- model 2
- model 3

Models will have their custom fields like miles/km, transmission type, body style, color and so on.

Germany
- model 1
- miles
- transmission
- color
- model 2
- miles
- transmission
- color
- model 3
- miles
- transmission
- color

Adding all this manually is quite a task if you have 50 countries, 15 models, 5 custom fields = 3750 entries. Is there a way to automate adding new categories and fields like this? Or any other suggestions for a Classifieds setup like this?

Perhaps in the future, we would also like to separate by private sellers / dealers.
