"18 days of sales" is listed under the Model S/X section. It would be highly misleading for S/X to be, say, 40 days of sales and Model 3 be 12 days of sales, and then write, under Model S/X, "Our deliveries increased sequentially to 17,722 as we continue to prioritize inventory reduction (working capital management). As a result, our total new car inventory levels have fallen to just 18 days of sales...". I'd say almost criminally misleading. I guess they could get away with it for including the word "total"?
