I have already told y'all the story a friend of mine, a Polish POW related to me. One of the Polish officers captured in his camp spoke very good German. The Germans asked him why and he replied that he had to learn the language so he could attend the Mercedes Benze factory mechanics' training course. The Germans assigned him to maintain the camp commandant's staff car, and he did so, faithfully. Until he succeeded in stealing a German officer's uniform and the camp tailors created a German enlisted man's uniform. And then one day he and one of the other POWs dressed in the uniforms and drove the commandant's Mercedes to Switzerland.
I'll bet that they did not let them keep the car.
