My Model 3 delivery date just updated to 9/20 - 10/4, so I am about 2 - 4 weeks away from delivery (No VIN assigned though). I set my payment method to cash, as I was seeing that this might speed the process along, even though I will actually be financing. My concern is that I will be selling my current car and using that as part of my down payment, so I don't really know what that will be until I actually get an offer on my car. I don't want to sell it too early and have to rely on other means to get around, especially if my delivery date changes again. What have you guys done? Should I go ahead and start the financing process now and hope my delivery date doesn't change? Or better to wait until I actually have a VIN # assigned to me?
