To estimate the price of the 2017 Bentley Bentayga W12 6.0L Twin Turbocharged W12 Speed, I started with the new car price of the same model in 2025, which is SAR 1386000. Considering a depreciation rate of 10% per year, the car would have depreciated approximately 70% over 7 years, bringing the estimated value to around SAR 415800. Next, I looked at the accepted offer for a 2019 Bentley Bentayga V8 4.0L W12 Speed with 39000 km, which was SAR 449000. Given that the 2017 model has higher mileage (119300 km) and is older, its value would be lower. I also considered the listed price of a similar 2017 Bentley Bentayga W12 with 162000 km at SAR 400000. Given the lower mileage of the car in question, its value would be slightly higher. Combining these data points, I estimated the market price.
