To estimate the price of the 2014 Kia Cerato I4 1.6L LX (Base) with 139,000 km mileage, I first considered the selling prices of similar cars. A 2013 model with much higher mileage (336,000 km) sold for 10,000 SAR, while another 2013 model with 183,945 km sold for 23,500 SAR. A 2015 model with 97,500 km sold for 30,000 SAR, and a 2015 model with 158,000 km sold for 34,500 SAR. The 2016 model with 159,000 km sold for 33,500 SAR. These prices suggest a range for similar cars in average condition. The 2014 model listed for 23,000 SAR with 130,000 km provides a reference point, but listed prices are typically higher than selling prices. Considering the depreciation and the condition, the estimated market price for the 2014 model should be slightly lower than the 2015 model with similar mileage, around 27,000 SAR.
