I started by examining the selling prices of similar cars. The most relevant data point is the 2016 Kia Sportage I4 2.0L with 120,000 km, sold for 34,000 SAR in January 2024. This car is similar in engine size and variant but has slightly lower mileage than the target car. Another relevant data point is the 2016 Kia Sportage I4 2.4L with 91,400 km, sold for 39,500 SAR in October 2023. Although it has a larger engine, it provides a reference for the market value. The 2.4L variant with 154,000 km sold for 44,000 SAR in May 2024, indicating a higher price for higher mileage and engine size. For listed prices, the 2.0L variant with 120,000 km was listed for 40,000 SAR, and the 2.0L with 172,000 km was listed for 43,000 SAR. Considering the target car's mileage of 135,000 km and good condition, I estimate its market price to be slightly higher than the 34,000 SAR sold price but lower than the 40,000 SAR listing, around 37,000 SAR.
