Fun fact: That little triangular window between the rear door and the C-pillar on modern Audis actually dates back to the Ro 80.
I know this. Audi took over NSU in '69, and every Audi sedan designed after 1972 has this window, without exception.Is this something you know, or percieve? Either way, i BARELY see it. Styling attributes can be borrowed from many sources, especially this far apart via time.
