Hello Philipp, in a Publication the Page Repeater allows you to render a page multiple times, filtering a specified visual by a different slice each time. 

In your scenario you will need first to add a Slicer with the Manufacturer attribute; then, from the page that you want to repeat, go to the Page Repeater option and add a new slicer, in this case it would be the Model attribute , and set the interactions accordingly (see Page Repeater.png). In the attached example we have a placeholder, at the top of the page, with the selected Manufacturer, and another placeholder with the Model, then a Grid, 

In this example, we will get a publication for the selected Manufacturer (slicer value); with only the specified pages being repeated, in this example different pages by Model.
