The car to be estimated is a 2018 BMW X6 with unspecified trim, average condition, and 75,000 km mileage. The closest selling price is for a 2018 BMW X6 Mkit I6 3.0L Twin Turbo with 116,800 km, sold for AED 109,000 on 2024-10-10. Another 2018 BMW X6 35i X-Drive with 144,067 km sold for AED 125,000 on 2023-09-21. Considering the mileage and unspecified trim, the estimated price should be lower than the 35i variant but possibly higher than the Mkit due to lower mileage. The accepted offer for a similar Mkit variant was AED 114,000. Listed prices for 2018 X6 35i variants range from AED 115,500 to AED 159,750, but these are typically higher than selling prices. Given the data, a reasonable estimate for the car in question, considering its lower mileage and average condition, would be around AED 120,000.
