Well there is were you are wrong
There was a 144 Grand Luxe 1970 made for Germany!
I only seen pictures of it,but it has "Grand Luxe" badge (not sure about fenders)at the rear atleast in the old style writing same as in "overdrive" and "automatic" for -->1970
It had the steelblue-metallic paint and black leather and the "S"engine.
So we can probably thank the germans that there is such a model because it was probably a request from them to start making them.
