Query: Not really worth it.

This book isn't too bad overall, but don't go getting any silly ideas like you are going to be able to build this thing for anything like a hundred pounds (about a hundred and fifty US dollars), because it isn't going to happen. You need access to a lathe and a welder, as well as drills and other tools, which you are assumed to already own. The amount of money you would end up spending on it, you would be better off buying a second hand one, as I doubt you will learn much from this book that you didn't already know. So overall, I'm not sure if it's worth bothering with, especially when the author's other book : "Build you own sports car for as little as 250 and race it" is available. That's a much better choice in my opinion- it really teaches you a thing or two.
