I wasn't expecting to see your response starting with 529xxx. 531xxx was mentioned just a couple of posts ago to compare. I have read vehicles don't always deliver VINs sequentially, but havent seen things jump around by that margin before under normal circumstances.Vin is 529XXX. Not sure how to find the build date.
As for build date, quoting Google "The build date for your Tesla vehicle is shown on the vehicle certification label located on the driver's side door pillar."
Thanks
