To estimate the price of the 2017 Mercedes A250 I4 2.0L Turbocharged with 54100 km, I first considered the selling prices of similar cars. The 2015 models with higher mileage (139000 km) sold for AED 40000 and AED 32000 recently. These prices suggest a lower baseline for older models with more mileage. Next, I looked at the listed prices of 2017 models. A 2017 model with 128000 km was listed for AED 58000, and another with 184000 km was listed for AED 53000. These listings indicate that the market expects higher prices for lower mileage. The 2018 models with similar mileage to the target car are listed around AED 90000 to AED 104750, but these are not sold prices. Considering the target car's lower mileage and the depreciation from new, I estimate the market price to be slightly lower than the high listings but higher than the older sold prices.
