To estimate the price of the 2021 Kia K5 GDI I4 2.5L LXS (Mid), I first considered the selling price of a 2022 Kia K5 I4 2.0L LX (Base) with higher mileage and average condition, which sold for SAR 52,000. This car is a lower variant and has a smaller engine, so the target car should be valued higher. Next, I looked at listed prices of similar cars. A 2021 Kia K5 I4 2.0L LXS (Mid) with 76,000 km was listed for SAR 73,000, and a 2021 Kia K5 I4 2.5L EX (Top) with 29,000 km was listed for SAR 72,500. The target car, being a mid variant with a larger engine and lower mileage than the 2.0L LXS, should be priced between these two. Considering the mileage and variant differences, I adjusted the estimate slightly lower than the 2.5L EX but higher than the 2.0L LXS. The 2021 Kia K5 I4 2.5L LX (Base) with 111,000 km was listed for SAR 60,000, which also supports a higher valuation for the target car due to its better variant and lower mileage.
