To estimate the price of the 2016 Mercedes S400 with 145000 km mileage, I first looked at the selling prices of similar cars. A 2015 Mercedes S400 with 94000 km sold for AED 112000 in November 2023, and a 2014 model with 117036 km sold for AED 90000 in June 2024. Given the higher mileage and older year, these prices suggest a depreciation trend. Next, I reviewed listed prices of similar cars. A 2016 model with the same mileage is listed for AED 119999, but this is likely higher than the actual selling price. Other 2015 models with similar mileage are listed between AED 89000 and AED 111000. Considering the car's condition is not good, I adjusted the estimate downwards. Factoring in the depreciation and the condition, I arrived at a reasonable market price estimate.
