To estimate the price of the 2020 Kia Optima I4 2.4L GDI (Base) with 134000 km mileage, I first looked at the selling price of a similar 2018 model with higher mileage (202000 km) which sold for SAR 31000 in August 2024. Given the 2-year difference and lower mileage, the 2020 model should be valued higher. Next, I reviewed listed prices of similar cars. A 2020 Kia Optima I4 2.4L GDI (Base) with 144000 km was listed for SAR 43500, and a 2020 Kia Optima I4 2.0L GDI (Base) with the same mileage was listed for SAR 47500. Considering the 2.4L engine variant and the average condition, I adjusted the price downwards. Additionally, a 2018 model with 181000 km was listed for SAR 49500, but this is likely an overestimate. Factoring in the depreciation and the average condition, I estimated the market price accordingly.
