SOLD! Thank you for your interest.
I have -zero- "new, in box" sets of OEM BMW self-leveling center caps (like the Rolls Royce ones that are always level).
These center caps are not available in the US yet; I ordered too many when I ordered a set for myself from Europe.
The sets retail for about $87 apiece and fit the 2018+ BMW lines with the 5x112 bolt pattern (F90 M5, G30, G12, F48, F39, G01, G02, G05). Asking $85 per set (each box comes with four wheel caps).

Hit me up, if you are interested.
Thanks
