I talked to Mark Leddington about this.
He told me that the "sweet spot" is between 775 and 825 cars a year, above that overtime costs go up and quality suffers.
If they ran 2 shifts (6 am to 13:00 and 13:00 to 20:00) they could comfortably build 1200 to 1300 a year, but to do that would mean adding people with skills that only they, MMC, can train. Steve has talked a lot about apprentices and training, so perhaps the 1300 mentioned on the website is an ambition.
