Clearly the VIN does not predict order of delivery... Although I am a techie and keep grasping at that straw myself - in the absence of any other clue as to when I will get my X... can't help myself!This doesn't make since, we see 51xx being delivered but we have others below 3xxx who are still waiting.
I can certainly understand folks frustration who have ordered very early and are still waiting for their X - when others that ordered later have theirs. Some evidence from the posts seems to point to the batch theory - Tesla producing vehicles based on options. Makes complete sense in a manufacturing environment. Additionally I'm sure that the seat and FWD problems have caused some mfg disruptions.
