To estimate the price of the 2019 BMW X7 XDrive40i with 49000 km mileage, I considered the following data points: 1) An offer accepted for a similar 2019 BMW X7 40i with 96850 km at AED 190000 on 2024-03-26. 2) Listed prices for similar 2019 BMW X7 40i models with higher mileage (96700 km and 96850 km) at AED 195000 and AED 205000 respectively. 3) The listed prices for 2019 BMW X7 50i variants, which are higher due to the more powerful engine, ranged from AED 225000 to AED 339000. Given the lower mileage of the target car and its average condition, I adjusted the price slightly higher than the accepted offer but lower than the listed prices to reflect a realistic market value.
