Congratulations Gandalf on your beautiful new Xfire, and a warm welcome to the forum. I may be wrong but I think you are the first from France. There are many from the UK and a couple from Switzerland.
To answer a couple of your questions that haven't been answered yet, yes the US Xfires come out of Germany too (slowly). My roadster left the factory on 30 August and it's still not in the US yet.
Some of our friends in the UK have had the same question about the luggage. Apparently it's just in the US. There are a couple of threads talking about luggage (touring gear). It is interesting to note that in the new Crossfire brochure they show a picture of the luggage by itself with the caption, "Available high performance travel gear, designed specifically to fit in the cargo area, maximizes available space. (See dealer for details.)"
That wording leads me to believe that they are leaving their options open for discontinuing it as a standard item at some point. That is just my opinion based on the word "available". (I'll put the picture and caption in my album. It is small but you should be able to expand it).
