The car in question is a 2015 BMW M4 I6 3.0L Twin Turbocharged coupe. We have no direct selling prices or offers accepted for similar cars, so we rely on new car prices and depreciation logic. The 2025 BMW M4 Coupe 3.0T starts at SAR 456,500. Assuming a 10% annual depreciation, the car would depreciate approximately 90% over 9 years (2015 to 2024). This results in a depreciation factor of 0.387 (0.9^9). Applying this to the new car price: 456,500 * 0.387 = 176,761.5. Rounding to the nearest integer, the estimated market price is SAR 176,762.
