Just got an email from my DS: "Your Tesla has completed production and is just waiting final inspection before it can be shipped down to San Diego. Sometimes this inspection only takes 1 day and sometimes it can take a week. As soon as I see it has cleared the inspection and is ready to ship, I will let you know.". That accounts to why there seems to be a variation of production to completion time. Personally I hope they take their time with the inspection to make sure they get it right before shipping it off!
