To estimate the price of the 2021 BMW M2 CS with 41800 km mileage, I considered the listed prices of similar cars. The closest match is a 2021 BMW M2 CS with the same mileage listed for AED 329000. Another 2021 BMW M2 CS Pack with the same mileage is also listed for AED 329000. A 2021 BMW M2 Competition Pack with slightly lower mileage (39500 km) is listed for AED 259000. For older models, a 2020 BMW M2 Competition Pack with 40500 km is listed for AED 245000, and a 2020 BMW M2 with higher mileage (74000 km) is listed for AED 225000. Considering the condition and mileage of the target car, and the fact that listed prices are generally higher than selling prices, I estimate the market price to be slightly lower than the listed price of the closest match.
