A 911 from the Emirates… maybe you have some answers for me…

Hello together, I love eugenelle at the moment with an elf from Dubai. The vehicle is in a clean condition with a comprehensible history. I do not want to start a discussion here about imports from the Emirates, but would like to ask if one or the other here has a few tips for me. Basically my questions concern transport, the registration and the financial processing. 1) Does someone have here a tip which forwarding agency a good job at this point I have already researched in various places on the net, the opinions and recessions have partly been very mixed. Maybe one or the other has already had good experiences and can give a tip here. 2) Which papers do I need to allow the vehicle in Germany. Is there such a kind of vehicle letter in the Emirates? The owner has a kind of vehicle certificate/vehicle letter which is finally a plastic card. The owner has no COC papers, but if my research is important, they can be applied for at Porsche for a fee of 300 €. Are other papers necessary in addition? (Custom documents are of course a matter of course when importing) 3) Does anyone have experience with paying for a vehicle in the Emirates? The seller is a private person whom I of course do not know and cannot assess. Is there the possibility of a self-evident I have here in Germany also an acquaintance of the family in Dubai, but I would ask him only in case of emergency to take over the financial business for me, to transfer the money to his family, so that the local can pay the vehicle cash. Maybe one or the other has a good tip for me. I would be very happy if one or the other could pay the car cash. he can put a good advice here. Greetings Al
