I`ve found this photo, i`m not sure, but the red cars on both photo`s look very similar, are they the actual same car? If they are, there`s other cars on this photo that might give the year away. But i agree, early 80`s is looking likely, so i was about 10 years out with my first guess. This photo looks like it was taken at the same time..more cars (and shop fronts)
