Usually they make them in batches.
What bothers me is my 23,4xx vin with white on white isn't delivered, while in this topic alone I see 23,5xx and 24,2xx white/white already delivered. I'm sure my car was made in that batch.
To be honest Mike Holiday, you might want a July build. I think the cars made this month have a much lower chance of quality assurance. Last month they were popping out thousands of vehicles with the same alignment issues.
