The car in question is a 2015 Kia K3 I4 1.6L (Diesel) Prestige (Mid) with 255000 km mileage and in average condition. The only data point available is a 2017 Kia K3 I4 1.6L (Diesel) Prestige (Mid) with 123990 km listed for SAR 47000. Considering the 2015 model is older by 2 years, we apply a depreciation rate of 10% per year. The 2017 model's price would be reduced by 20% to account for the age difference, resulting in an estimated price of SAR 37600. Additionally, the higher mileage of the 2015 model (255000 km vs. 123990 km) suggests a further reduction. Assuming a 10% reduction for the high mileage, the estimated price is adjusted to SAR 33840. Given the average condition, a final adjustment of 5% is applied, resulting in an estimated price of SAR 32148.
