To estimate the price of the 2018 Kia Optima I4 2.4L LX (Mid) with 94000 km mileage, I first looked at the actual selling prices of similar cars. The 2018 Kia Optima I4 2.4L with 202000 km sold for SAR 31000 on 2024-08-03. Given the higher mileage, this car would be valued lower than the target car. The 2016 Kia Optima I4 2.0L with 290000 km sold for SAR 26500 on 2024-02-23, which is also lower due to older model and higher mileage. Next, I considered the listed prices of similar cars. The closest match is a 2018 Kia Optima I4 2.4L LX (Mid) with 94000 km listed for SAR 51000, but listed prices are generally higher than selling prices. Another similar car, a 2018 Kia Optima I4 2.4L LX (Mid) with 149000 km, was listed for SAR 44000. Considering the lower mileage of the target car, its value would be higher. Factoring in the condition and the average depreciation, I estimated the market price accordingly.
