To estimate the price of the 2018 Mercedes C200 I4 2.0L Turbocharged Standard sedan with 168000 km mileage, I considered several data points. First, I looked at the selling prices of similar cars. A 2017 Mercedes C200 with 77670 km sold for 93000 SAR in October 2023, and another 2017 model with 60000 km sold for 80000 SAR in February 2024. A 2020 model with 66000 km sold for 112500 SAR in February 2024, and another 2020 model with 56000 km sold for 125000 SAR in August 2024. A 2017 convertible with 115000 km sold for 113000 SAR in May 2024. Given the higher mileage of the target car, I adjusted the price downward. I also considered the listed prices of similar 2018 models: one listed for 75000 SAR and another for 70000 SAR. Taking into account the higher mileage and the fact that listed prices are generally higher than selling prices, I estimated the market price accordingly.
