Something I did NOT know....

World War II
General Motors produced vast quantities of armaments, vehicles, and aircraft during World War II for both Allied and Axis customers. By the spring of 1939, the German Government had assumed day-to-day control of American owned factories in Germany, but decided against nationalizing them. During the war, the U.S. auto companies continued to be concerned Nazi Germany would nationalize American-owned factories.^{[citation needed]}
GM's William P. Knudson served as head of U.S. wartime production for President Franklin Roosevelt, who called Detroit as the Arsenal of Democracy. The General Motors UK division, Vauxhall Motors, manufactured the Churchill tank series for the Allies. The Vauxhall Churchill tanks were instrumental in the UK campaigns in North Africa (ironically often being used to attack German logistics units using Opel trucks). Bedford Vehicles manufactured logistics vehicles for the UK military, all important in the UK's land campaigns. In addition, GM was the top manufacturer of U.S. Army 1½ ton 4x4 vehicles.^[4]
Nevertheless, while General Motors has claimed its German (Opel) operations were outside its control during World War II, this assertion appears to be contradicted by available evidence. General Motors was not just a car company that happened to have factories in Germany; GM management from the top down had extensive connections with the Nazi Party, both on a business and personal level.^[5] During war Opel's Brandenburg facilities produced bombers JU-88, trucks, land mines and torpedo detonators for Nazi Germany.^[6] During War years GM declared it had abandoned its Nazi subsidiary , and took a complete tax write-off because of which they have received tax reduction of "approximately $22.7 million" or about $285 billion in 21st-century money. After the War GM collected some $33 million in "war reparations" because the Allies had bombed its German facilities ^[7] for which they have earlier declared complete tax write-off and received tax reduction.
American GM Vice President (later Colonel) Graeme K. Howard was a committed Nazi, and expressed such views in his book, America and a New World Order. Adolf Hitler awarded GM boss James D. Mooney the Order of Merit of the Golden Eagle for his services to Nazi Germany. General Motors’ internal documents show a clear strategy to profit from their German military contracts even after Germany declared war against America.
Defending the German investment strategy as “highly profitable”, Alfred P. Sloan told shareholders in 1939 GM’s continued industrial production for the Nazi government was merely sound business practice. In a letter to a concerned shareholder, Sloan said that the manner in which the Nazi government ran Germany "should not be considered the business of the management of General Motors...We must conduct ourselves as a German organization. . . We have no right to shut down the plant."^[8]
After 20 years of researching General Motors, Bradford Snell stated, "General Motors was far more important to the Nazi war machine than Switzerland ... Switzerland was just a repository of looted funds. GM-Opel was an integral part of the German war effort. The Nazis could have invaded Poland and Russia without Switzerland. They could not have done so without GM.”^[8]

Yup...if we ever went to war again...all of the car manufacturing plants would be making our armored transport vehicles! Thats what got us out of the last depression

Fords german facilites were also taken over... but it appears Ford did not directly profit off of that facility during the war as did GM

hmmm looks like Ford has always been the resilient one huh?
