Register custom taxonomy from a Advenced custom field option page

Consider instead a single, hierarchical taxonomy, where the top level terms are brands such as Nike/Adidas/etc, and child terms are models.

Otherwise you face a scaling issue, as the number of brands increases, so do the number of taxonomies, and so does the complexity of the code behind the scenes.
