A friend of mine spent most of WWII in a German prison camp. The Germans discovered that one of the Polish officers interned there was a Mercedes Benz trained mechanic. So they informed that officer that his duties in the camp would be to maintain the camp commandant’s staff car.

He did indeed maintain the car, faithfully. And then one day he put on a stolen German officer’s uniform, got another prisoner to don a German enlisted man’s uniform to act as his driver. And, displaying the appropriate imperious attitude, they drove that staff car all the way to Switzerland.

Audacity works, if you are very well prepared.
