So a little bit of a background, I live in the Seattle area and early August I placed an order online for a M3 MSM SR+. At the time was happy with my decision and excited for the car. Fast forward to today, after watching some youtube videos online, I decided I really wanted the LR AWD version of the car instead. I looked on the tesla new inventory page and saw they had recently added new 2020 MSM LR AWD to the page. So I called my SA and asked him if it was possible to switch my SR+ order to the LR one in the inventory. He looked up the information on the car and apparently the car itself has a VIN but he also told me that his was more like a placeholder. The car still needs to be built and most likely if I order now, it'd be delivered in the next quarter (similar to cancelling my current order then reordering a new trim). My question is why would a car shows up in the inventory with a VIN is only being built now and I may have to take delivery in the next quarter? I was hoping to swap out my current problematic car by this month. Should I go ahead and take the risk and swap with the car with the VIN? Anyone have more insight into these inventory cars?
