Bought this for my 7 year old who is very interested in transport. This book is great for him- its very detailed but I would not advise it for younger children because of its depth- but for those interested in transport- children or not; a great book.
I really don't need this book- I've got two kids and far too many baby tip books. But it has lovely pictures and good advice and ideas. I'd recommend if unlike me, you don't already have a library of these books- otherwise pretty much what's in This book can be found in all the others.
