I'm not really into cars. I heard about this guy's research about Ganz before he wrote the book, and I was interested. Before purchasing it, I was worried that it would be purely technical and engineering in content with little about Ganz himself. But now that I'm reading it, it's just great - a perfect balance of interest, not drifting away from Ganz; this Schilperoord guy really did his research. It's also wonderful to see that the translation is good, which is unfortunately unusual with these foreign-language books. What's more, the reader also appreciates that it's not a conspiracy type of book: that is, it doesn't over-emphasise that Hitler stole Ganz's Volkswagen.
A great read, well worth the time and price. My only setback was that it doesn't have an index, which is useful for reference after one's finished reading it, but the book itself makes up for that.
