Buy the book. A true McLaren fan has the book.
A fanatic has the original release for his bookshelf and a reprint to thumb through and a few others for future gifts.
If you consider it, the book is relatively not that expensive considering that it costs less than a 1/18 UT model, or even less than some of the 1/43 models and of course way less than the 1/12 models.
You will not regret purchasing a copy of the book. You can find for around $69.00 unopened mint or $49.00 opened mint.
