To estimate the price of the 2014 Audi Q5 TFSI Quattro I4 2.0L Turbocharged 45 TFSI quattro Luxury (Mid), I started with the new car price of the 2025 Audi Q5 45 TFSI S-Line Quattro, which is SAR 252,000. Given that cars depreciate by approximately 10% per year, I calculated the depreciation over 10 years (2014 to 2024). The formula for depreciation is: Depreciated Value = New Car Price * (1 - Depreciation Rate)^Number of Years. Using this formula: Depreciated Value = 252,000 * (1 - 0.10)^10 = 252,000 * 0.3487 = 87,872.4. Considering the car's mileage of 67,500 miles and its average condition, I adjusted the price slightly downwards to account for these factors.
