Found this for CLE models: https://modernspare.com/product/2023...e-kit-options/

Anyone see other options? I'm trying to see if anything can potentially fit in the trunk under the top mat.

 

Might be able to get one of those collapsible ones, similar to what Porsche uses.

My main concern with the one linked is that it might take up too much trunk space, or maybe if no one sits in the back, can put it where the rear seat is so the trunk isn't occupied, not ideal though.
