To estimate the price of the 2018 BMW X3 M Standard with 80,000 km mileage, I analyzed the listed prices of similar cars. The 2018 BMW X3 M xDrive M40i with similar mileage is listed for AED 110,000. This variant is likely more expensive due to its higher trim level. The 2019 BMW X3 M Standard with slightly higher mileage is listed for AED 166,000, but being a year newer, it would typically command a higher price. The 2017 BMW X3 M Standard with higher mileage is listed for AED 64,500. Considering the target car's average condition and its position between the 2017 and 2019 models, I estimate its market price to be slightly higher than the 2017 model but significantly lower than the 2019 model, taking into account the depreciation and condition.
