Toyota corolla's and camrys don't have tow hitches either. I own a BMW 528i and it doesn't have a tow hitch.
It's lol-tastic that every car you mention is available with a hitch here.
BMW 528i (removable hitch, so not in the photos, but on the used car sold here): Brugt BMW 528i 3,0 aut. til salg - Bilbasen
Toyota Corolla (also removable, but you can see the connector): Brugt Toyota Corolla 1,4 D-4D Luna til salg - Bilbasen
Totyota Camry: Brugt Toyota Camry 2,2 Executive til salg - Bilbasen
These were all three the first hits when I searched for used cars of that type.
I wonder who has persuaded Americans that small cars can't tow small trailers. Was it the companies that make very good margins on Pickups? Ford’s Margins: It’s All About the Trucks
