Take your car with you immediately (300km)

Hi, here’s the thing, I’m still getting started and I have a car in sight. Unfortunately, it’s about 300km away from me. I can’t let go and WILL have it. I’m still confused with the order… I want to do it so that I can pick up the car immediately if I’m on the spot. So don’t drive twice for re-registration, etc. Is that possible? I imagine this something like this: 1. I call the dealer and tell him that I want to take the car with me immediately when I buy it. e. 2. I go to the insurance company and get me the so-called double card. So, but since I don’t have the vehicle tickets yet, so I don’t get the double card either? That means again that I get the papers first, get back, get the double card again, and then pick up the car again? 3. But I’d like to do it all in one. Ginge that? How about these five-day badges? People help me, I really want to get through nander. As I said: – Driving, paying, license plates and then changing with the bought car… That would be my favorite. But this change of registration, license plates, insurances somehow hinders me. Would you be grateful for an explanation. 😉 Ahoi!
