With 1/3 model X and 2/3 model S, the 5100 cars in transit would be about 1700 X's. Add that to the 4625 delivered X's and you have 6125 "completed" X's for the quarter. Add the 2600 or so 2015 and Q1 deliveries and you get to 8700 or so total deliveries/completed cars which still is 1000-2000 vehicles less than the highest VIN we see delivered. Where are all those missing vehicles? Dealer demos, scrapped cars from build flaws? I know VINs are not assigned in order but still makes you wonder about the high VIN count we see posted by deliveries.
