I'd go for 1984 Mini Mayfair as described - chrome bumpers, tints, headrests. Does not have 85+ side indicators. Or wheels. But has wheel arch extensions which suggests 12" wheels as introduced in 84. Photo too small/fuzzy to be sure but I think grille is what I call the old Morris format, so - apart from stray Austin grille badge and the wing indicators - compare with this photo of 86 Mayfair.
