These vehicles are generally not rust-prone compared to contemporary vehicles of the time, however rust tends to occur in the usual places where moisture and mud tend to accumulate. Areas to check are below the windscreen on both sides of the car, the firewall where the heater is mounted, and the lower sills, especially behind the back wheels and below the front doors. The vinyl roof cover which was a popular and standard fitment on GL models (delete option only) was also a source of water entrapment, creating the possibility of rust in the "A" pillars and gutters. KC models were more prone to rusting than KB models. This can be attributed to the KC panels being made in Australia from different steel than the KB's imported panels.
