In the 1980s, Hot Wheels had gotten into a controversy with General Motors' Chevrolet Motors Division. In 1982, the Chevrolet Corvette had ended the curvaceous Mako Shark body-shape design that had been in production for almost 15 years, and GM announced that the Corvette would be redesigned. In 1983, Chevrolet started to produce the all new C4 Corvette but had assembly line problems which pushed production back 6 months causing GM's Marketing Department to label all 1983s as 1984s once they got production perfected so it would seem to the public that the all-new C4 Corvette came out early rather than late. But Hot Wheels saw what the new model of Corvette was going to look like before GM's official unveiling, and they designed a die cast version of the 1984 Corvette. GM was angered and almost pulled its licensing with Mattel, but this controversy helped Corvette buffs see what the new Corvette was going to look like. The 1984 Corvette production ran for 1. 5 model years covering half of the remaining 1983 model year and ending on time for the 1985 model year.
