To estimate the price of the 2020 Mercedes E300 I4 2.0L Turbocharged Top with 143691 km mileage, I started by looking at the selling price of a similar 2022 model with 13000 km mileage, which sold for SAR 245000 in July 2024. Given the 2-year difference, I applied a depreciation rate of 10% per year, reducing the value by 20%, resulting in an adjusted price of SAR 196000. Next, I considered the listed prices: a 2018 E300 Standard with 50000 km listed for SAR 153000, a 2022 E300 Top with 13000 km listed for SAR 250000, a 2020 E300 Standard with 2450 km listed for SAR 194000, and another 2020 E300 Standard with 2000 km listed for SAR 260000. The 2020 Standard models' prices suggest a higher value for the Top variant. Factoring in the higher mileage of the target car, I adjusted the price downward. Combining these data points, I arrived at a final estimate.
