To estimate the price of the 2019 BMW 520 M Sport with 169500 km mileage, I first considered the selling prices of similar cars. A 2018 BMW 520 M Sport with 160000 km sold for AED 69000 in February 2024, and a 2019 BMW 520 M Sport with 83000 km sold for AED 121000 in May 2023. Given the higher mileage and average condition of the target car, its value should be lower than the 2019 model sold for AED 121000. The 2018 model's selling price of AED 69000 provides a lower bound. Considering the depreciation and the car's condition, I estimate the price to be slightly above the 2018 model's selling price but significantly below the 2019 model's price. The listed prices of similar 2018 and 2019 M Sport models range from AED 72000 to AED 95000, which supports this estimate. Therefore, I estimate the market price to be around AED 75000.
