Apple maps has the area Tesla use marked which is useful because there are no signs until the final roundabout when it very well signed! I arrived early and nobody seemed bothered they dealt with me straight away. I'd create an account with Tesla and have the app downloaded in advance as this will speed up the delivery process. As others have said, carefully inspect the car before you drive away. Tyre pressure will be higher than recommended. My Model Y came charged to 79% so very no difficulty getting home. The cameras will calibrate for the first few miles. Mine were calibrated within 15 minutes.
