Ford offered a completely redesigned body for its cars in 1952. The new body featured a one-piece curved windshield, a full-width rear window, protruding round parking lights and a round three-bladed spinner in the center of the grille bar. The Mainline was Ford's entry model; its spartan interior included only one sun-visor and an armrest only on the driver's door. This car has over 200,000 miles on the original engine.Source - AACA Museum
After the introduction of the Model T in 1908, Ford began its successful journey into the realm of being one of the most recognizable automobile manufacturers of all time. With Henry Ford handing over the reigns to Henry Ford II, the 50's would be lead with high efficiency engineering and an old way of personalized management.
Below the Customline and the Fairlane in Ford's lineup, was the Mainline. This vehicle had a relatively short life span, produced from 1952 to 1956. The mainline was designated as a sedan, even though it was available with two doors. This of course, attracted many of the sport car enthusiasts because of its smooth and modern look and also for it's handling during a daily drive.
The Mainline's engines were a six cylinder producing over 100 horsepower and an eight cylinder producing over 110 horsepower.Kyle McMullen
