I Did ask a similar question in another thread.
My '18 is SGM. It is just a hair darker than I'd prefer but a pretty thin hair.
I am considering trading for a similar used '22/'23 with as low miles as possible.
I'm wondering the difference between the 2 colors. I've been looking closely lately at the CbG pics here. Not real thrilled with what I'm perceiving. The CbG doesn't seem to have near, if any, of the Mica WOW that SGM has. Actually, from the pics, I'm not seeing much at all metal sparkle.
​​​​​​This would be a deal breaker.
I actually did see a '22 SGM with, shockingly Zero miles recently. But it was on the other whole coast and the non Alcantara seats. Red interior though. 🤪 I actually considered it for a few seconds.

Yes CBG has metal flake, however the metal flake blends in with the grey, Not a large pop on the metallic.
