To estimate the price of the 2017 Kia Rio I4 1.4L LX (Base) with 155000 km mileage and in average condition, I first looked at the selling prices of similar cars. The most relevant data points are: 1) A car with 114733 km in good condition sold for 17000 SAR on 2023-11-09, 2) Another similar car with 114733 km in good condition sold for 26000 SAR on 2023-11-10, 3) A car with 172000 km in average condition sold for 26000 SAR on 2024-03-06, and 4) A car with 163000 km in average condition sold for 28224 SAR on 2024-05-24. Given the target car's higher mileage and average condition, I adjusted the price downwards. I also considered listed prices, such as a car with 155000 km listed for 22000 SAR and another with 153000 km listed for 25000 SAR. These listings are generally higher than actual selling prices. Taking all these factors into account, I estimated the market price accordingly.
