Hello dear community members, I am new here and still young with my 18 years I would have a question as I find nothing on the internet. And I want to sell my CLK. An acquaintance wants to buy this with a purchase contract and monthly payment. Only he does not want to register it but wants to leave it in public, without registration. What problems can I get when the car is logged off, the purchase contract is already signed by him. If he is already the owner and e s would be his problem or do I get the penalty for parking on public road of the registered car? Thank you in advance for the answers!
