First, I considered the selling prices of similar cars. The 2017 Mercedes C200 sedan with 77670 km sold for 93000 SAR in good condition. Another 2017 C200 sedan with 60000 km sold for 80000 SAR in average condition. A 2017 C200 convertible with 115000 km sold for 113000 SAR in average condition. Lastly, a 2015 C200 sedan with 312000 km sold for 62500 SAR in average condition. The target car is a 2017 coupe with 102000 km in average condition. Coupes generally have a higher value than sedans but lower than convertibles. Considering the mileage and condition, I adjusted the price downwards from the convertible's selling price and slightly upwards from the sedans. The listed prices were higher, but they are not reliable as they are often inflated.
