I'm at 496 today :). However, I'm lucky enough to have mine ready to pick up at the dealer. I just need to get to Iowa, which will likely be in a week or so. It's been a super frustrating process. I bailed on my original Platinum order because I was tired of waiting and wanted it by this summer. I also didn't want to pay an additional $8k. Ticked about the non-LED taillight thing. My 2017 mid-level Tahoe has LED taillights. I don't see any case against Ford. Everything is subject to change at any time. I suspect that having LED taillights in the order guide, etc. was just a miscommunication between product mgmt and the doc people. Happens all the time.
Anyway, good luck with yours! I'll post some picks when I get it.
