During the production of the "Type 53", there were subtle changes to the body and trim. On cars produced after the summer break in August 1975 (for the 1976 model year), the conventional two wiper system changed to a single wiper which parks on the passenger side of the windscreen, while the driver also benefited from improved, lighter, steering linkage. In August 1977 (for model year 1978) the separate front side marker and turn signal, changed to a combination wrap-around orange lens. At the same time, behind the doors the B-pillar colour changed from body colour to black, which was thought to give the car a more pleasing profile. Other mid-life changes include the move from chrome bumpers with rubberised end caps to a plastic-coated one-piece wrap around bumper. In 1979, the one-piece "flag" style outside mirrors transitioned to a two-piece shrouded mirror.
