To estimate the price of the 2020 Kia Pegas I4 1.4L LX (Base) with 70000 km mileage, I first considered the actual selling price of a similar car with 50000 km mileage sold for SAR 23500 on 2023-09-15. Given the additional 20000 km on the target car, I adjusted the price downwards slightly. Next, I reviewed the listed prices of similar cars with varying mileages: 65000 km listed for SAR 33000, 87500 km for SAR 30500, 89687 km for SAR 35000, 99800 km for SAR 38000, 104117 km for SAR 29000, and 119000 km for SAR 30000. These listed prices are generally higher than actual selling prices. Considering the average condition and the mileage of the target car, I estimated a fair market price slightly lower than the average of the listed prices but higher than the actual selling price due to the market trend and the car's condition.
