Walter, where is the 5000 here?

Just saw the movie Grand Canyon http://www.imcdb.org/movie_101969-Grand-Canyon.html yesterday evening on TV, so I haven't got any pic of them, but I spotted three -very well visible- background Audis. Two of them, a 1980 Audi 5000 C2 [Typ 43] and a 1980 Audi 4000 B2 [Typ 81], are parked along the road during the first part of the movie, before Mack's Lexus starts to break down. The third one, a 1984 Audi 5000 C3 [Typ 44], is visible in that thumbnail http://www.imcdb.org/vehicle_118746-Eagle-Model-10.html , so we can use this picture for it.
