Blocker, some glaring mistakes like ADR plate should be BODY plate for Acacia Ridge vehicles. Lots of other small errors and when I get a chance i'll go through it.
Biggest problem is trying to simplify something that is fairly complicated in some areas. The ID part of the book is not yet finished and up to at least 12 x A4 pages already. I reckon you are better off scrapping the Sandman ID and building a "how to determine it isn't" guide. I've found this a much better approach. Stops 60% of queries at the first hurdle.
