Adjusting for the year difference and mileage, the 2016 model should be slightly lower. Another relevant data point is the 2015 Mercedes C200 I4 2.0L Turbocharged Top with 312000 km sold for 62500 SAR in March 2024. Considering the mileage difference, the 2016 model should be higher. The listed price of a similar 2016 model with 100000 km is 88500 SAR, but listed prices are generally higher than selling prices. Factoring in these data points, I adjusted the price to reflect the market conditions and the specific condition and specs of the car in question.
