To estimate the price of the 2016 Mercedes C200 I4 2.0L Turbo Charged Standard with 185000 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 good condition, and another 2017 model with 60000 km sold for 80000 SAR in average condition. A 2015 model with 312000 km sold for 62500 SAR, and a 2014 model with 194000 km sold for 41000 SAR. The 2017 convertible model sold for 113000 SAR but is less relevant due to its body type. The listed prices for 2016 models were 93000 SAR and 90000 SAR, but these are higher than actual selling prices. Considering the car's age, mileage, and condition, I adjusted the price downwards from the 2017 models and slightly above the 2015 and 2014 models, factoring in depreciation and higher mileage.
