Ford Escort Ghia (Needed) How?

Hello! I am new here in the forum and also fresh starter. I have now saved (as a trainer) 2,000 € and wanted to buy a used car. The car is a Ford Escort Ghia with mileage: 86tkm TüV New until 12/2011 ABS / Servo / Airbag for 1850€ (in the annex you have a picture of the car) I liked the car immediately (external / inside and also the pure mileage) Now my question: The car has new TÜV! If I now for example the dealer at the next on Monday (by appointment) pay the money and he gives me the keys what do I need to drive the car to my home? My father said that would be quite simply that I could just drive home without insurance and everything (is only a KM) but I have read I have to get a cover card from the insurance company and a transfer license from the road traffic office is that correct or does it run differently? (A little confused because of the transfer). M fG Severen // Good slide
