Ordering procedure Tesla – comfort/settlement sought

As a Tesla newcomer I would have a question for the (order) experienced old rabbits here in the forum. I need a new car in winter, recommendation of the service staff: β€žCar already order now, secure delivery and above all conditions secured. Said done, vehicle put together on the homepage, leasing selected, runtime, driving performance and deposit entered and order completed. In the meantime order confirmation received, as far as everything great, beautiful new Wel t. Now to the (for me) unusual: only the purchase price is shown in the order confirmation. No reference to the chosen leasing, its conditions or even additions (price for more/minor kilometers, etc.). According to the telephone statement of the service employee this is quite normal, before April I can not make a bank request at all, everything can be changed at any time and everything is fine, no problem, I should look into the app again in October and then can the Is this always the case? What did I actually “secure” about conditions? Can I now be surprised by the prices and conditions that then apply, as well as by the technical state or equipment of the vehicle at the end of the year? I’m a little confused. Every comforting shoulder clipper (experience report) is gratefully accepted by the newcomer from the old world. ;-))
