Beyond Driven
I wish people wouldn't call the non-Obsidian as "flat black". Flat implies to me a matte finish. Like some of those matte black vinyl wraps people do.
The standard black is more of a "gloss black" or "jet black" or "piano black".
And yes, it can look great if kept clean and waxed, but it does show dust/dirt/scratches more than the metallic finishes.
I think of obsidian black as a darker version of "midnight silver".
Perhaps you would prefer "solid black" for the standard solid black?
Either way, as a previous owner of a steel grey (later renamed midnight silver) Model S, there is no way I would own either one of those again (my favorite color of the limited palette from which we have to choose) or a black car (either black presently available) without an investment in Modesta. Opti-Coat Pro Plus was fine for the steel grey, but for black you've pretty much got to go all in, and the best there is for black cars appears to be Modesta. Pain in the keyster to apply (extra days, extra money), but it is thicker in the end and does have the longest credible warranty, so there's that.
