To estimate the price of the 2020 Bentley Bentayga 4.0L V8 TC V8, I first considered the new car price for the 2025 model, which starts at AED 860000 for the 4.0L V8 variant. Applying a 10% annual depreciation over 4 years, the estimated value of a new 2020 model would be approximately AED 585000. Next, I reviewed the listed prices of similar cars. The closest match is a 2020 Bentley Bentayga with 32700 km listed for AED 390000. Other 2020 models with similar mileage and specs are listed between AED 390000 and AED 475000. Given the average condition of the car in question, I adjusted the estimate slightly lower than the average of these listings to account for potential negotiation and condition factors.
