I analyzed the selling prices of similar cars first. The closest match is the 2015 Mercedes C200 I4 2.0L Turbo Charged with 122695 km sold for 57500 AED on 2024-08-30. Another similar car, a 2015 Mercedes C200 2.0L V4 with 162000 km, sold for 49000 AED on 2024-03-23. Considering the mileage and condition of the target car, which is 140400 km and average condition, it falls between these two examples. The 2016 models with similar specs and conditions sold for prices ranging from 59000 AED to 75000 AED, but they are newer. The accepted offers for 2015 models range from 60000 AED to 72000 AED, but these are not actual selling prices. Given the data, I estimate the market price of the target car to be slightly lower than the highest selling price of a similar 2015 model due to its higher mileage and average condition.
