I've also seen it and apart from one or two scary pictures of MCDC Matt's done a really good job!
And yes I am biased,Matt having used several of my pictures, my car's and Eden Park Raceway but it's still a colourful, well presented and handy reference guide with a very comprehensive glossary!
Even the likes DC may learn something!
