I looked back at my emails from Tesla, and not long after my order date there was an email saying it's not too late to have my trade-in quoted. I clicked the link and filled out the form, and it said the trade-in portal would be re-opened within 2 days, and so it was. Right now the portal is sitting their waiting for me to either enter my trade in details, or click the button saying I'm not trading in a car. Meanwhile my delivery is on hold. I expect that at some point someone will call me to ask whether I'm going to proceed with trade in valuation. I have no idea how long that will be.How do you open the trade in portal? And what does putting your order on hold this way actually mean? Will they hold the car indefinitely (assuming they won't change the VIN).
