To estimate the price of the 2021 BAIC BJ40 Champion (Top) with 100000 km mileage, I considered the listed prices of similar cars. The 2021 BAIC BJ40 Premium (Base) with 58000 km is listed for AED 78500. The 2020 BAIC BJ40 Flagship (Mid) with 50200 km is listed for AED 88000. The 2023 BAIC BJ40 Flagship (Mid) with 46000 km is listed for AED 103000, and the 2022 BAIC BJ40 Flagship (Mid) with 29500 km is listed for AED 90000. Given that the Champion (Top) variant is higher than the Premium (Base) and Flagship (Mid) variants, and considering the higher mileage of 100000 km, I adjusted the price downwards from the listed prices. The average of the listed prices is approximately AED 89875. Considering the higher mileage and the fact that listed prices are generally higher than selling prices, I estimated the market price to be slightly lower.
