I agree with the other reviewer that this is not a book of serious scholarship on motorsports, its history or development. Yet I find his judgement of it overall unduly harsh. The book is not of the kind to be read from cover to cover and in that sense it is not a page turner. It does have plenty of amusing vignettes from the world of motorsports and I feel that it deserves 4 stars in the way it succeeds at its stated goal - to provide the interested reader with some lighthearted trivia (entertainment) on the sport.
And some of the stories are truly too bizzare to be made up - the Tripoli Grand Prix of 1933 being but one example - and definitely come into the trivia section of knowledge someone interested in motorsport will likely want to acquire. I find it is a decent read, too - much above the standards of the Sun - but a piece of brilliant prose it is not (nor should a reader expect this, given the title and topic).
It covers the period from 1894 to 2006 and while most stories come from the world of Grand Prix racing (F1 from 1950 on), there are others from endurance events such as the 24 hours of Le Mans, the Paris to Peking, etc. as well as some more left field events such as the 2006 Indian Autorickshaw Challenge.
