Here is a tip for when you find your VIN in the code: Call your shop, tell them you saw the VIN online, and ask to schedule the delivery.
Once you see the VIN, they can see when the truck is supposed to arrive. They need a day or so to inspect and detail the cars.
You should be able to ask for a delivery day the day after your car arrives at the shop.
They may tell you that the truck may be delayed due to weather or logistics, and that's why your delivery date will be tentative. Still, ask them to put you on the schedule asap. I did, and as a result I'm the first one to get my car: 10am the day after it arrives, when the door opens that morning
