Given the lack of specific data points such as selling prices, offers accepted, and listed prices of similar cars, I will use the depreciation logic based on the new car prices. Assuming a new 2014 Mercedes E200 I4 2.1L Turbocharged (Diesel) Standard sedan had an approximate price of 200,000 SAR when new, and considering a depreciation rate of 10% per year, the car would depreciate as follows: 2015: 180,000 SAR, 2016: 162,000 SAR, 2017: 145,800 SAR, 2018: 131,220 SAR, 2019: 118,098 SAR, 2020: 106,288 SAR, 2021: 95,659 SAR, 2022: 86,093 SAR, 2023: 77,484 SAR, 2024: 69,736 SAR. Given the high mileage (341,202 km) and average condition, I would further reduce the estimated price by approximately 20% to account for these factors, resulting in an estimated price of around 55,789 SAR.
