Nazi officers may have driven and owned cars like those in the war years, but they weren't produced specifically for them. Mercedes happened to be in Germany, and they produced lots of material for the Germans. I'm sure some employees were Nazis, but not all Germans were. Most supported the regime because they had little choice, some simply because it was their home country. You can't hold everyone accountable for the acts of a ruthless dictator who had most of the country spell bound. I've talked to German people who lived through it -- most had little idea of the atrocities going on until after the war. Some did, like the townspeople near the death camps, and turned a blind eye, though there's not much they could have done. I remember one lady (just passed this year) well. She was a young girl during the war and when Hitler came to power. She remembered that the German people fell for Hitler's rhetoric mainly because he brought them out of a long economic slump, created by the Treaty of Versailles ending WWI. The Allies set things up for another war, though that wasn't the intent. The intent was to make Germany pay for the war, and it ruined the nation for years (more or less the intent). Woodrow Wilson argued against retribution, but the European powers wouldn't hear it. They endured the brunt of the war, but refused to acknowledge that they were in part responsible for it as well.
