I started by examining the selling prices of similar cars. The most relevant data point is the 2014 Renault Fluence I4 1.6L with 173,000 km sold for 9,000 SAR on 2023-11-15. This car is very similar in year, engine, and condition to the target car. 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. Considering the target car has higher mileage (191,000 km) than these examples, its value would be slightly lower. The 2012 model with 218,000 km sold for 13,000 SAR on 2023-10-08, indicating older models with higher mileage can still fetch a decent price. Based on these comparisons, the estimated market price for the 2014 Renault Fluence 1.6L with 191,000 km is around 9,500 SAR, considering its age, mileage, and condition.
