To be precise, it doesn't come with all of the updates. It does have USB in the glovebox, includes a 64GB flash stick, and the metallic finished scroll wheels. Along with the previously noted updates, such as auto-dimming side mirrors.
It does not have the updated console and associated USB updates.
No recent buyer has checked for a single piece rear casting. Doing that is simply lifting the rear seat bottom to check for a centered joining bracket and stamped steel mounting tabs vs cast aluminum where the seat frame bolts down. I've seen the older two piece casting on early 2021 VINs person, and it's easy to tell once you know to look for that center bracket.
I also expect a modified trim panel that is more easily removed on tow equipped vehicles.
Sorry I meant it as "look at all these updates it has" not trying to imply it has all of the updates we've talked about in this thread.
