Query: The Book's Just Like the Car, Unfulfilled Potential

Perhaps I was expecting too much from this book but then again perhaps it was written for Corvette fans unfamiliar with the GTP car and the IMSA series. It's really nothing more than a picture book that spends as much time discussing the Corvette's competition in the IMSA series as it does the Corvette itself. I was expecting much deeper insight into the technical aspects of the car including design, development, construction, and lot more information about the engines. I also expected a lot more technical pictures of the car's construction and components. It's unfortunate the author only scratched the surface of such an interesting GTP car. I'll give the book a D+ at best.
