A more accurate title of this book should be "Keith Tanner's Lotus 7 Replica Build Diary"
As another reviewer has mentioned, this is more of a companion book to Ron Champion's book. That statement shouldn't discourage anyone from purchasing this book though.
Champion's book was more of a how-to cookbook, whereas Tanner's is a variation of the recipe. It is quite interesting to see another build, especially a US-based build (Champion's being basically a UK build).
This Miata-based build diary is a great way of seeing a different kind of variation. I, for instance, am building one around a Toyota 4AGE powerplant, and it is good to see how Tanner was deviating (and working around) the cookbook approach that Champion did. With a little ingenuity, one could use the "problem-solving techniques" that Tanner did.
That is not to say that Tanner outlined any techniques; rather, his diary was exactly that: a build diary. He shows what problems he encounters, and how he goes about solving it. The reader then has to infer what thought processes Tanner used, and the reader should be able to come up with his own.
I would have given this book 4-stars for the content, but it earns an extra star because of the way Keith Tanner writes. He manages to inject a lot of humour and wit in his writing. So when the time for your build comes and when the frustrations start pouring in (and believe me, they will start pouring in), go re-read this book and enjoy.
You will also notice that the author has this stupid grin [hey! His words, not mine... I think...] plastered on every picture that he appears in. You can even see that silly grin through one of those pictures where he's wearing a full-face helmet. Can't blame him though, as that Seven sure looks like it will plaster an idiotic grin on anyone. Heck, as I read the book, his infectious "stupid grin" has migrated to my face as well.
There is a child-like enthusiasm that Keith Tanner has, and it shows on practically every page. And it is contagious -- after all, I think boys will be boys, and this is one helluva toy. I wonder how many times the author has written VROOM-VROOM in this book? I could remember quite a few. :)
If you are building a Seven, and especially if you are building a Seven in the US, this makes a great read. It is a worthwile companion (not a replacement) to Ron Champion's book, and any builder should have this in his library.
