The Chrysler Corporation was heavily involved with war production and when the war drew to a close, plans were put into effect to resume vehicle production. Like most companies, there was no time to retool for new models, so the new postwar models were largely upgraded and restyled prewar models. Immediate production was delayed due to material shortages created by the war. The days following the end of the war found the United States very enthusiastic and eager to purchase products they could not purchase during the war years. Automobiles were eagerly sought after so the companies continued building the prewar models – and most would not introduce new models until 1949. The revamped older models were well received and vehicle sales during the years of 1946 to 1948 were at an all time high-especially considering sales during the later prewar years were dampened by the Great Depression.
