To estimate the price of the 2019 BMW X3 xDrive 30i with 180104 km mileage, I considered several data points. First, a similar 2019 BMW X3 30i M Kit with 99600 km sold for AED 122500 on 2024-07-07. Given the higher mileage of the target car, its value would be lower. Another 2018 BMW X3 30i M sport with 71000 km sold for AED 155000 on 2023-10-20, but this car is in better condition and has lower mileage. The accepted offer for a similar car with the same mileage and specs was AED 84000 on 2024-08-11. Listed prices for similar cars with higher mileage range from AED 75000 to AED 85000. Considering these factors, the estimated market price is based on the accepted offer and the lower end of the listed prices.
