The car in question is a 2021 Opel Grandland X Innovation I4 1.6L. We have the new car price for a 2025 model of the same variant, which is AED 109,000. Assuming a 15% annual depreciation, the estimated value for a 2021 model would be calculated as follows: 2025 to 2024 depreciation is 15%, reducing the price to AED 92,650. From 2024 to 2023, another 15% depreciation reduces it to AED 78,752.5. From 2023 to 2022, another 15% depreciation reduces it to AED 66,939.625. Finally, from 2022 to 2021, another 15% depreciation reduces it to AED 56,898.68125. Rounding this to the nearest whole number, the estimated market price is AED 56,899.
