To estimate the price of the 2014 Audi S7 TFSI Quattro V8 4.0L Turbocharged Standard, I started with the new car price of the 2024 Audi S7 Standard Sedan, which is SAR 432500. Assuming a depreciation rate of 10% per year, the car would depreciate approximately 60% over 6 years (2014 to 2020) and an additional 10% for the next 4 years (2020 to 2024), totaling around 70%. This gives a depreciated value of around SAR 129750. Additionally, I considered the listed price of a similar car with the same specifications and mileage, which is SAR 85000. Given that listed prices are generally higher than actual selling prices, I adjusted the estimate downwards. Combining these data points, I arrived at a final estimate.
