I started by focusing on the selling prices of similar cars, particularly those closest in year, engine size, and condition to the target car. The most relevant data point is the 2016 Renault Fluence I4 1.6L with 310,000 km sold for 17,000 SAR in January 2024. This car is the same year and variant as the target but has higher mileage. Another 2016 model with 125,000 km sold for 20,000 SAR in late 2023, indicating a higher value for lower mileage. The 2015 models with similar engine size and condition sold for between 11,500 SAR and 15,000 SAR, depending on mileage. Given the target car's mileage of 213,500 km, which is between the two 2016 models, I estimated the price to be slightly lower than the 17,000 SAR car due to the lower mileage but higher than the 2015 models due to the newer year.
