To estimate the price of the 2018 BMW X6 xDrive35i Twin Turbo M kit V6 3.0L M Sport, I first considered the selling prices of similar cars. A similar car with higher mileage (116800 km) sold for AED 109,000 on 2024-10-10, and another with 104,000 km sold for AED 115,000 on 2024-10-27. The car in question has lower mileage (80,000 km) and is in good condition, which suggests a higher value. An offer was accepted for a similar car at AED 114,000 on 2024-09-25, which supports this range. Listed prices include AED 115,500 for a similar car with 104,000 km, indicating a market expectation around this value. Considering these data points, the estimated price is slightly higher than the highest selling price due to better condition and lower mileage.
