A tesla dealership rep mentioned that sometimes people will (1) order a car online and then (2) when it’s time to arrange delivery, they can’t get their finances in order… so they lose their current spot and car gets passed to the next person in the queue (or posted on the website)
Could be that as well.
I ordered a M3 and was looking at a 4 month wait, but I lucked out because of the above (at least, that’s what the rep told me). Ended up taking delivery within 1 month instead of 4.
