I bought this for £5 off Amazon a day or so after GT5 was launched (as I write this review it has sold out already). The package arrived in just 3 days and is a fantastic little book. A fact-packed book that basically gives you essential hints and tips on how to drive each track and with plenty of full-colour screen shot illustrations. The print size is a bit small, but then again it has to pack a lot of text and screen shots into a small A5 page. You get a chapter on the relative merits of the different drive set ups: front engine-rear wheel drive, front engine front wheel drive, all wheel drive, mid-engine rear wheel drive and rear engine rear wheel drive. Hints on how the camber settings can work for you and against you and tips on how to brake, steer and accelerate into and out of different types of corners. However, there is no specific detail on the various models of cars - the first couple of chapters are general driving hints and guidance on how to choose a set-up option. The vast majority of the book is about the tracks within GT5.
When you get into the real meat of the book, it goes through each of the GT5 tracks in sequence. The book is laid out in "Landscape" format and on the first page of each track you get an aerial map of the track layout, which is labelled with a series of numbered track points. On the page below you get a series of numbered sections that correspond to those track points, giving an explanation of how to tackle that feature and a colour screen shot to show you will be seeing in front of you. The added bonus is that you even get the plan and hints for the Top Gear track as driven by 'The Stig' and advice on how to deal with the corkscrew s-bend at Laguna Seca.
If I had to be picky I would say the text and screen shots are a bit small, but I guess printing it in A5 format keeps the costs down. If you have access to a colour photocopier or your home printer doubles up as a scanner, you could always zoom it up to A4. At the risk of being ultra-picky, there are some minor spelling and grammar errors which I suspect are a result of minor translation blips by the japanese author Akitomo Sugawara, it is all very very minor stuff and you can fully understand what is being said, but I just wanted to be honest and mention it. The best feature of this is the fact that it has been printed in landscape and is spiral bound, so it lays perfectly flat when opened and can also be propped up vertically A-frame style like a desktop calendar beside the screen when you are practising.
All in all, a great little handbook that is easily worth a lot more than the £5 that I paid for it. The tips inside have already shaved seconds off the best lap times I achieved at Nordwand and High Speed Ring when driving them in the Prologue version. This book has already become scarce since GT5 was released in the UK in Nov 2010 ... if you can get hold of a copy, buy it.
