To estimate the price of the 2011 BMW X5 4.4L V8 AWD TwinTurbo xDrive 50i (Top) with 178650 km mileage, I considered the following data points: 1) A similar 2011 BMW X5 4.4L V8 Twin Turbo with 237500 km sold for AED 19000 on 2024-07-15. 2) An offer accepted for a 2011 BMW X5 4.4L V8 with 204500 km was AED 31000 on 2023-10-07. 3) A similar car listed for AED 27000 but not delisted. Given the actual selling price of AED 19000 for a higher mileage car, the accepted offer of AED 31000, and the listed price of AED 27000, I estimate the market price to be closer to the actual selling price but slightly higher due to lower mileage and similar condition.
