The car to be estimated is a 2018 Mercedes C200 convertible with 150,000 km mileage in average condition. The closest data point is a 2018 Mercedes C200 coupe listed for AED 73,500 with 163,000 km, which is a similar body type but not a convertible. The selling prices of similar sedans from 2016 to 2020 range from AED 59,000 to AED 143,000. The 2019 models in average condition sold for AED 107,000 and AED 112,500, while 2016 models in average condition sold for AED 59,000 to AED 67,000. Considering the convertible body type typically commands a premium over sedans, and the car's average condition and high mileage, the estimated price should be slightly higher than the 2016 models but lower than the 2019 models. The listed price of the 2018 coupe at AED 73,500 provides a reference point, suggesting a market price slightly below this due to the convertible's higher desirability but offset by its condition and mileage.
