I started by focusing on the selling prices of similar 2016 Kia Sportage models with the same engine size and variant. The most relevant data point is the 2016 Kia Sportage I4 2.0L LX (Base) with 120,000 km sold for 34,000 SAR on 2024-01-06. Another similar car, a 2016 Kia Sportage I4 2.0L LX (Base) with 241,811 km, sold for 35,000 SAR on 2023-10-18. Considering the target car's mileage of 173,660 km, it is closer to the first car but with higher mileage, suggesting a slightly lower price. The listed prices for similar cars range from 41,000 to 43,000 SAR, but these are typically higher than actual selling prices. Therefore, I estimate the market price to be slightly below the 34,000 SAR mark, considering the higher mileage and average condition.
