I was recently contacted by Haynes after placing an order for the book. I was told the book will only go into printing sometime in August. So, we'll have wait a little bit longer, I suppose.
I just assumed that since they had it on their website now that it was available, they even have it included in there limited time sale! Seems they may be advertising something they don't have yet.
If you can read German, then there is a German manual available if you can't wait for Haynes (or they slip with their publication date). I bought mine from
The German version of amazon.co.uk I find the book good enough to use for most repair/maintenance issues with my basic German. Its best feature is that its full of drawings, so you don't need to read the German text, provided you know what you are doing, and just need an insight before pulling things apart.
