The MGA is a sports car that was produced by MG from 1955 to 1962. The MGA replaced the MG TF 1500 Midget and represented a complete styling break from MG's earlier sports cars. Announced on 26 September 1955 the car was officially launched at the Frankfurt Motor Show. A total of 101,081 units were sold through the end of production in July 1962, the vast majority of which were exported. Only 5869 cars were sold on the home market, the highest export percentage of any British car. The MGA is a body-on-frame design and used the straight-4 "B series" engine from the MG Magnette saloon driving the rear wheels through a 4-speed gearbox. Suspension was independent with coil springs and wishbones at the front and a rigid axle with semi-elliptic springs at the rear. Steering was by rack and pinion. The car was available with either wire-spoked or steel-disc road wheels.
