Vehicle delivery (What can you expect?)

Hello together, after the delivery of the vehicle to the dealer of SEAT would interest me what I can expect. For me this is the first new car and I am very excited. What should be the least that is done? What is more or less common? What would be “extras” or distinguishes a particularly good handover? How long does such a handover usually take? How would I be interested in you? Maybe with your personal pro and contra.
