To estimate the price of the 2022 BAIC BJ40L I4 2.3L Turbocharged Champion (Top) with 52500 km mileage, I considered the listed prices of similar cars. The closest match is a 2022 BAIC BJ40L I4 2.3L Turbocharged Champion (Top) with 44000 km listed for SAR 110000. Another 2021 model with 55000 km is listed for SAR 87000. A 2022 Flagship (Mid) variant with 46000 km is listed for SAR 89000, and a 2023 Champion (Top) with 26000 km is listed for SAR 90500. Given the target car's mileage and condition, I adjusted the price slightly lower than the 2022 Champion (Top) with 44000 km but higher than the 2021 model with 55000 km. The 2022 Flagship (Mid) and 2023 Champion (Top) listings also helped in fine-tuning the estimate.
