Only if there's downstream QA/QC concerns; even then, that doesn't preclude the Fatherland from such shortcomings.
With all that said, it is an automobile designed in Germany by a German manufacturer so in-essence it is
a German car (whatever all that may mean & infer).
I find that the company's core philosophy & standard-operating-procedure matters more'so than "where" & "what" all.
Now, if I was paying mondo-moolah for some super-duper luxo' saloon or exotic sports-car, obviously I would find it more "special" if it was actually assembled in the U.K., Germany, Italy, Japan, etc.
