To estimate the price of the 2014 Mercedes E200 I4 2.0L Standard with 171000 km mileage, I first looked at the selling price of a similar car: a 2013 Mercedes E200 I4 2.0L Turbocharged with 176000 km mileage sold for SAR 47500 in February 2024. Given the similar condition and specs, this provides a strong reference point. Next, I reviewed listed prices of similar cars. A 2014 Mercedes E200 I4 2.0L with the same mileage is listed for SAR 68000, but listed prices are generally higher than selling prices. Another 2014 model with 192000 km is listed for SAR 70000, and a 2014 model with 115000 km is listed for SAR 77000. Considering the higher mileage of the target car, these listed prices suggest a lower actual market value. Additionally, a 2013 model with 176000 km was listed for SAR 49500 but sold for SAR 47500, indicating a typical reduction from listed to selling price. Factoring in these data points, the estimated market price is derived by adjusting the selling price of the 2013 model upwards slightly due to the newer model year but considering the similar mileage and condition.
