I am in the same boat, but ordered a MYP a couple months ago as a backup. As we have no idea if our X will ever come, and I currently have no car, I may end up taking the MYP to take the pressure off on the X delivery and have something to drive in the mean time. Problem is if I take the Y now, I will likely miss out on the $10,000 tax credit starting January 1. You just can’t win with Tesla
