The car to be estimated is a 2018 BMW X5 M Kit XDrive 50i with a 4.4L V8 engine. The closest data points are the selling prices of 2018 BMW X5 35i 3.0L I6 Twin Turbo M kit, which sold for AED 87000 in July 2024. These cars have a smaller engine and are less powerful than the 50i variant. The accepted offers for the 35i variant range from AED 103000 to AED 135000, with the most recent offer being AED 113500 in October 2024. Given the 50i's higher performance and engine size, it should be valued higher than the 35i. Considering the depreciation and the market trend, the 50i variant should be estimated higher than the highest accepted offer for the 35i, but not excessively so due to the average condition and high mileage. Therefore, a reasonable estimate for the 50i variant would be around AED 125000.
