Of the "not bright/saturated colors," I think this one is the best. Still prefer green/yellow/blue/red, but this is definitely above Dune's color to me. And with the burnished bronze‽ Now I want my trim color to be burnished bronze!
The vehicle really is a work of art. They did a fantastic job from top to bottom. On the bespoke edition end of things, I think there's a place for it, the recent Dune edition is a great example of that, although not to the same high end standard.
With the R2 coming, it's probably not a bad idea for Rivian to push the R1 series even higher end with more luxury features in order to separate the two lines. The R1S will be high luxury SUV and the R1T will be more and more off-road capable with various interior trim levels.
