Tesla has closed vehicle production for the last week of Q1. Cars that were made prior to shutdown are on their way to service centers for customer deliveries. VINs numbers on the website that are in the Existing Inventory are either on the lots, or on transport vehicles being delivered to the centers. Existing Inventory does not mean that those cars are sitting in that service center parking lot. IMHO all cars will be sold because there will be no more North America production for 6 weeks as all new production vehicles will be going to Europe as in the previous 4 quarters.
