First, I considered the selling price of a 2015 Mercedes S400 with 94000 km mileage, which sold for AED 112000 on 2023-11-08. This car is similar in variant and condition to the target car. Next, I looked at a 2014 model with a higher mileage of 117036 km, which sold for AED 90000 on 2024-06-01, but it was in average condition. The accepted offer for a similar 2015 model with 81000 km was AED 115500 on 2024-04-30. For listed prices, a similar car with 81000 km was listed for AED 130000 but delisted, indicating it might be overpriced. Another similar car with 99118 km is currently listed for AED 107000. Considering these data points, the selling prices and accepted offers are more reliable, suggesting a market price around AED 112000 to AED 115500. Given the target car's lower mileage of 77700 km, I estimate its price slightly higher within this range.
