To estimate the price of the 2015 Kia Sorento I4 2.4L EX (Mid) with 215542 km mileage, I focused on the selling prices of similar cars. The closest match in terms of engine size and variant is the 2016 Kia Sorento I4 2.4L, which sold for SAR 32500 (mileage: 324000 km) and SAR 34000 (mileage: 190000 km). Considering the 2015 model year and the mileage of the target car, I adjusted the price slightly lower. The 2016 Kia Sorento I4 2.4L with 223000 km sold for SAR 35000, which is a good reference point. Given the target car's higher mileage and being a year older, I estimated a slightly lower price. The V6 variants generally sold for higher prices, so I focused on the I4 variants for a more accurate estimate.
