How to form categories correctly?

Question

Prestashop

Hello, I’m terribly dumb, I can’t figure out how to create categories for spare parts in Prestashop.
Background: there is auto-dismantling (they sell parts), there are a lot of parts both for specific brands and models, and by type (body, electric, etc.).

It turns out such a scheme: (as I see it) i.e. there is, for example, a bumper, it refers to bodywork, bodywork, in turn, refers to a specific model, but also to the entire brand (brand) as a whole.
The problem is actually in the Body parts section, let’s say I’ll make a brand (brand) through the Brand in Presta, the model is most likely as a category, but how to separate the body parts so that each model has its own and not produce hundreds of the same category for each model? After all, let's say a bumper from one model is not suitable for another model.

Filter by models. Categories can be made as follows: Body parts -> Bumper. Inside the Bumper subcategory, you can select the desired model.
