To estimate the price of the 2016 BMW X6 xDrive 35i I6 3.0L Twin Power Turbo (M Kit) M Sport (Top), I first looked at the selling prices of similar cars. The 2018 BMW X6 xDrive 35i (Base) with similar specs and mileage sold for SAR 153,000 and SAR 150,000 in October 2023. Given that the target car is a 2016 model, I applied a depreciation rate of approximately 10% per year. This results in a depreciation of around 20% over two years, bringing the estimated value to around SAR 120,000. Next, I considered the listed prices of similar cars. A 2016 BMW X6 xDrive 35i (Base) with 215,531 km was listed for SAR 105,000, and a 2016 BMW X6 xDrive 35i (M Sport) with 179,614 km was listed for SAR 115,500. Given the target car's M Sport trim and good condition, I adjusted the estimate slightly higher than the base model listings. Finally, I factored in the condition and mileage of the target car, which is in good condition with 179,614 km, aligning it closer to the higher end of the listed prices.
