My opinion on this book is that it is a decent book i mean yeah they explain cars but not about the cars that many people are interested in.First The author was talking about many of the German cars and i was mainly looking for JDM cars which is Japanese cars they are way more interesting.Next one thing that i really liked about the book and what the author did was put the specs of the different types of engines in the car such as how much horsepower and torque the car has which is a big plus when doing research on these cars.Last As a car enthusiast i am i mean he had some good cars on here but i give props to this guy to put some jdm cars but at the same time be didn't really talk a lot about them as the other cars and that was a big thumbs down for that part.So overall the book was alright but just for a reminder TALK MORE ABOUT JDM CARS the car community with fall in love with your book Chris if your talk more about the engines and go more deep into the specs of the car sheesh your book will be bought by so many car enthusiast.
