P3asa im a bit confused by your posts. You post above says confirmed build week but in the links it just talks about given a build week after 3 week. Im guessing that was a quick confirmed date than rather than the usual provisional one that you normally get after 3 weeks

At the present time my car no longer has a provisional build week its simply listed as a factory ordered car.
The exact quotes are "there is no scheduled built date"
" I cannot confirm this with you as the factory status only says factory ordered."
I use to have a provisional build week of first 46 then it slipped to 48 then to 50 now it does not list one so my dealer says.
