Eh, my VW GTI has a section on towing in the manual that says, paraphrased: "Don't do this, also, this is how you do it" and any U-Haul rental place will (poorly) install a tow hitch for their small box trailers, even on compact cars
I only did a quick search and didn't find the latest model. But for the previous model you can tow 1600kg with a Golf GTI in Norway. The tow hitch can be ordered factory installed
