To estimate the price of the 2017 Bentley Bentayga W12 6.0L Twin Turbocharged, I first considered the selling price of a 2019 Bentley Bentayga V12 with 92000 km sold for AED 364000 on 2023-08-22. Given the 2-year difference and higher mileage, I adjusted the price downwards. Next, I looked at listed prices of similar 2017 models: AED 350000 (same variant and mileage), AED 318000 (similar variant, higher mileage), AED 289500 (similar variant, higher mileage), AED 300000 (2018 model, higher mileage), and AED 306000 (similar variant, much higher mileage). The closest match in terms of variant and mileage is the AED 350000 listing. Considering the actual selling price and the listed prices, I estimated the market price by averaging and adjusting for the condition and mileage.
