To estimate the price of the 2018 Mercedes S560 Standard with 65000 km mileage and Japanese specs, I analyzed the listed prices of similar cars. The closest match is a 2018 Mercedes S560 Standard with 66400 km, American specs, listed for AED 130000 and delisted on 2024-05-03. Another similar car with 52000 km, American specs, was listed for AED 149000 and delisted on 2024-05-08. A Japanese spec car with 47000 km was listed for AED 215000 and delisted on 2024-07-19. A Japanese spec car with 113900 km was listed for AED 185000 and delisted on 2024-04-30. Considering the mileage and specs, the price should be closer to the lower end of the Japanese spec cars but higher than the American spec cars. Therefore, I estimate the price to be around AED 160000.
