To estimate the price of the 2020 Mercedes E250 E 250 CGI Standard convertible with 124000 km mileage, I considered the listed prices of similar cars. The closest match is a 2020 Mercedes E250 E 250 CGI Standard convertible with the same mileage listed for AED 239000. However, this is a listed price and likely higher than the actual selling price. Other listed prices include a 2019 Mercedes E250 Standard coupe with 69000 km for AED 99999, and two 2021 Mercedes E250 Standard sedans with 53700 km and 47500 km both listed for AED 139000. Given the higher mileage and the convertible body type, I adjusted the price downwards from the listed AED 239000 to account for depreciation and market conditions.
