To estimate the price of the 2014 Kia Rio I4 1.4L LX (Base) sedan with 297000 km mileage in average condition, I considered the following data points: 1. A 2016 Kia Rio I4 1.4L LX (Base) sedan with 124000 km in good condition sold for 29000 SAR on 2024-01-02. 2. A 2015 Kia Rio I4 1.4L LX (Base) sedan with 226000 km in average condition sold for 17000 SAR on 2024-03-05. 3. A 2016 Kia Rio I4 1.4L LX (Base) sedan with 234000 km in average condition sold for 22000 SAR on 2024-06-07 and 2024-06-09. 4. A 2016 Kia Rio I4 1.4L LX (Base) sedan with 228000 km in average condition sold for 18500 SAR on 2024-07-15. 5. A 2014 Kia Rio I4 1.4L LX (Base) sedan with 297000 km listed for 20000 SAR and another with 278000 km listed for 23000 SAR. Considering the higher mileage and average condition of the target car, I adjusted the price downwards from the 2015 model with 226000 km sold for 17000 SAR and the 2016 models with similar conditions and higher prices. The listed prices also suggest a range around 20000 SAR, but actual selling prices are lower.
