To estimate the price of the 2018 BMW X5 M xDrive35i I6 3.0L Twin Turbo charged Standard, I used the new car prices of similar models as a reference. The 2025 BMW X5 M Standard SUV starts at AED 612,000. Assuming a 10% depreciation per year, the car would depreciate approximately 50% over 5 years (10% per year). Therefore, the estimated value of a 2018 model would be around 50% of the new car price, which is AED 306,000. Given the car's average condition and mileage, I adjusted the price slightly lower to account for these factors.
