The disconnect of delivery dates, reservation numbers and VIN’s was due to part issues/manufacturing issues (i.e. bad parts, paint scratches, part shortages, etc.) so If your car was one of the “28” or had to be "reworked" you got moved back … if you had options/color/delivery location that was advantageous for batching you got moved up. No car will leave the factory less than Elon’s quality standard. Simple as that IMHO! What say you?
