To estimate the price of the 2020 Mercedes E300 I4 2.0L Twin Turbo Top with 81300 km mileage, I first considered the selling price of a similar 2022 model with 13000 km sold for SAR 245000 in July 2024. Given the 2-year difference, I applied a 10% annual depreciation, resulting in a 20% total depreciation, bringing the estimated value to SAR 196000. Next, I looked at listed prices: a 2020 Top variant with 143691 km listed for SAR 161000 and a 2022 Top variant listed for SAR 250000. The 2020 model with higher mileage suggests a lower value, while the 2022 model supports the depreciation estimate. Considering the mileage and condition of the target car, I adjusted the estimate slightly higher than the 2020 listed price but lower than the depreciated 2022 model value.
