Yes, that what you are thinking. I'm thinking the opposite - that not may wanted the basic white and that they therefore canceled it.I think it is because not many wanted basic black,
Btw: We have seen a few white RC cars out there. It is hard to tell, but I do really think it looks like they are basic white, not multi-coat pearl white. So this may return with the Model 3?
Btw II: We are discussing Model 3 here, so why do you have to bring up the price of metallic paint for Model S/X? Basic white if offered will probably be a none-cost option, like it was. Or it will be the multi-coat pearl white that cost $1500 on S/X. And what the cost if multi-coat on Model 3 will be, no-one outside of Tesla knows yet....
