Pretty sure that France closes down for August.
At least you'll get yours on a '15 plate
I believe the factory shuts for the first two weeks in August and the production line restarted this week. So I suppose that wont have helped! Though "yes" France does have a reputation for "closing" in August. Damn those foreigners )).
Though I suppose the latest reg. is always welcome (though private plate will be getting transferred at some point).
