So, based on what the pricing guide shows, you cannot order Thundernight Metallic with Tacora Red interior.
Had my heart set on that personally (had to switch to black leather with the blue stitching and ZTK), and online you can still configure a 2023 MY M240iXdrive in that color combo. Also shows the blue brakes which I wanted. The blue does seem to stay if you configure using non shadowline design, and then adding the extended shadowline. However if you configure it initially with the shadowline exterior vs cerium, it will go to the red calipers.
Why is it able to be built like that, but not configured using the pricing and ordering guide?
