I think your idea is good, in this case i do not need to take over loan since I can pay cash and the guy can pass the same money back to bank and can get release letter in day or two

A used car dealer would charge 1000 AED for this service

buyer and sell will go to used car showroom, the buyer will pay money to used car, who will keep the car, and make paper work between buyer and seller, after the loan is cleared the seller will pass clearing paper to used car company who will transfer the car to the original buyer...
let me know if someone else would like to share or confirm this info? Thanks
