I started by looking at the selling prices of similar cars. The most relevant data point is the 2014 Renault Fluence I4 1.6L Standard with 173,000 km sold for 9,000 SAR on 2023-11-15. This car is very similar to the target car in terms of year, engine, and condition, but has slightly lower mileage. Another relevant data point is the 2015 Renault Fluence I4 1.6L with 145,500 km sold for 11,500 SAR on 2023-10-22. This car is newer and has lower mileage, which justifies a higher price. The 2012 model with 218,000 km sold for 13,000 SAR on 2023-10-08, indicating that older models with higher mileage can still fetch a decent price. The listed prices for 2014 models were 16,500 SAR and 12,500 SAR, but these are higher than actual selling prices. Considering the target car's mileage of 191,000 km and average condition, I estimate its market price to be slightly lower than the 9,000 SAR sold price due to higher mileage and the passage of time since the last sale.
