I have a number of autocourses and I still feel that they are getting better with every passing year. If you have an interest in Formula 1 then you should have this book. It gives an overview of each team in the championship and really gets a great insight as to how their performances stacked up and what their expectations really were or should have been. The race guides are an indespensible piece of information for the serious fan, although they do occasionally miss outstanding performances from the middle or rear of the field, due to the majority of the focus being on the battle at the front, however most details are covered and in very good detail. The summary of the other racing series (F3000, F3, CART, NASCAR, etc) is a very worthwhile addition as it gives a good reference point without having to purchase other literature. Then there is the top 10 driver lists, they may not always be the rankings you expect, or agree with!, but they certainly are a good talking point, and quite well justified in most cases.
Overall the most complete annual book about Formula 1 and a complete necessity to any real fan.
