That's a very good question. I have wondered why they bother with issuing/assigning VINs so early. It seems to make the whole system inflexible. Example, what happens if your assigned car gets damaged before delivery, so you go to the back of the queue as all cards are assigned?Anyway, serious question - do they stick to the issued VINs? Or they will give you a different car with your configuration if it is available in the inventory?
