I started by examining the selling prices of similar cars. The most relevant data points are the 2012 Mercedes C200 I4 1.8L Turbocharged Standard with 181,000 km sold for 30,000 SAR in January 2024 and another with 205,000 km sold for 23,000 SAR in September 2024. The car with 205,000 km is very close in mileage to the target car and sold recently for 23,000 SAR. The car with 181,000 km sold for 30,000 SAR earlier in the year. Considering the target car's mileage of 199,500 km, its value should be between these two prices. The listed prices show a car with 205,000 km listed for 25,500 SAR, which aligns with the selling price of 23,000 SAR. Therefore, the estimated market price for the target car is closer to the lower end of the range, around 23,000 SAR.
