The history of 1940s Pontiac cars is uniquely split by World War II. After producing stylish 1941 and 1942 models, Pontiac shifted entirely to manufacturing anti-aircraft guns and tank parts. This hiatus makes surviving early-forties models particularly rare, as civilian automobile production didn't resume until the late 1945 model year. https://www.amerifreight.net/blog/1940s-pontiac-cars
