The 4S store requires you to pay a down payment. Do you want to ask if you want to pick up the car? If you don't just pay the down payment when you pick up the car, maybe the 4S store wants to collect your money first, and then you want to return the car or not apply for a mortgage, so you are in a passive position (because you have already paid the money).
If you are asked to pick up the car, you must pay a down payment. Hehe, that's all.
