Ok, good news is that what you can select for GT premium convertible matches precisely what my dealer have put in the build sheet back in December. So, they are either both wrong, or both got it right. High hopes!
Bad news is that some accessories seem to be gone. I was considering them, and now I'm less happy than I could be.

And honestly, given that Tonneau Caps (for convertible) are no longer included (according to the order guide), I would expect them to be found as an optional accessory for 2021 MY. But they're not in B&P either, so I'm genuinely puzzled.
I'm sure this information was available before the order page came up, but it looks like the 2021 Mustang still comes with Sync 3? In every trim? So no support for wireless Android Auto or Apple Carplay?
I wonder if they're not going to bring Sync 4 until the next gen... Hopefully they at least do one more mid cycle refresh to bring it aboard. Might finally get me to upgrade.
... Either that, or I'll just jump ship to the Camaro. It's already way cheaper AND it has wireless phone connectivity.
