Speaking with my dealer the car went into production in March so was not in the original production run - those cars started on the line in November. My VIN indicates car number circa 2500 but there is no way to confirm if the numbers are sequential off from the production line or initial orders etc.
The Ineos site is certainly not accurate regarding in production, contract signed etc. My car shows as still in production but my dealer tells me it is ready and waiting shipping - your dealer has a better handle on information than the website.
I have seen one customer who has not yet signed his contract but his dealer has confirmed it is on the way - interesting if he backs out
