The Mark IV continued to be one of the most distinctive cars on the American road. Subtle differences gave the 1975 models a new appearance, without tampering too much with the look of the car. The standard vinyl roof sported a new detail: the body paint color appeared between the vinyl roof moldings and the top of the windshield and roof edge trim. The vinyl roof moldings were color-keyed to match the vinyl roof, and had a thin chrome edge. This allowed the body color to contrast with the vinyl roof color, and provided definition to the lines of the roof if the body and roof colors were the same. Inside, the steering wheel spokes were revised and turned down at each end. The list of standard equipment for 1975 was expanded to include the Power Lock Convenience Group, Speed Control, and Tilt Steering Wheel, along with new-for-1975 Four Wheel Disc Brakes with Hydro-Boost Braking System. This eliminated the need for engine vacuum power assist, and improved overall braking performance and pedal pressure.
