WWII Impact on German Auto Industry - Paperback

This is a book about one mans survival during the Holocaust. I had the chance to interview the man they called Iron-Mike. He noticed I was driving an Audi and he asked me did I know the history of the car your driving. I thought he meant Carfax, but he was talking about the terrifying time he worked in their factories as a slave during the Holocaust. He started off telling me how BMW, Benz, VW, and Audit were founded and how they had to pay for the slave labor that was forced on him and other Jews.
