What impressed me most about Iacocca is his incredible frankness. He doesn't beat about the bush. Also, the book clearly depicts his clinging on to crucial values which allowed him to be successful in both fields: at work AND at home. How many businessmen working or even overworking manage to achieve what he has accomplished in the commercial world and yet keep a designated amount of time for his wife and kids consistently? Goes a long way to show how important it is set your priorities right.
As for the style of the book itself, it is fluent and comfortable to read.
True that the book is written in 1987 and the background is two decades old but it still provides interesting insight into both corporate and political America since he's one of those who has 'been there, done that!'. Try it out, it's much fun.
