If you read the other reviewer's ('Mad Matt') first paragraph, about not knowing much about the Skyline except its streetfighter 'reputation' and liking films such as Fast&Furious and so on, and if you think you're pretty similar, then as he says, this will probably be a good book for you.
Personally, it wasn't for me. I'm no great expert, but I do know a bit about Skylines, and this book did seem quite superficial - and certainly too in awe of the GT-R's 'reputation'. There are some good bits for sure, but if you already feel you know a little about the R32/33/34, then I'm not convinced you'll learn much more here.
