Obsidian Black and Silver Metallic are the two least popular colors. Small lots are killers in such paint shops, based on the set up time and tear down time, especially given they are metallic paints. Hence Tesla is wise to eliminate them for now. Again this tells us that most people are not paying the $49,000 base price, they are at the minimum paying up to $2,000 for paint upgrade.
I guess if they do not reintroduce it, you can claim that this is rare and difficult to find color when you want to sell it
