The dealer is THE best source. They can pull the visibility report and give you exactness.
This was mine pulled last friday. The dealer thinks itll be delivered between 24 and 30 Aug based off this BUT it didnt saybreleased which is the very last thing it needs to say to indicate it going into Transit. My dealer is only 6 hours from Dearborn so we shall see but I think It'll be delivered beginning of Sept TBH.
Of course, it's worth noting that it says Ford Confidential meaning some dealer sales managers might be reluctant to show you this. Having paid for my vehicle in full already I would've kick them in the nutz if they told me they cant show it though...
