To estimate the price of the 2022 Mercedes G63 AMG with 28400 km mileage, I considered the following data points: 1) An offer accepted for a 2022 Mercedes G63 AMG 5.5L V8, non-GCC spec, with 0 km mileage at AED 780000 on 2023-11-04. This car is newer and has no mileage, so it would be priced higher. 2) A similar 2022 Mercedes G63 AMG with the same mileage and Japanese specs listed for AED 650000. This is a close match and provides a good reference point. 3) Other listed prices for similar models: a 2020 model with 24499 km at AED 610000, a 2020 model with 23000 km at AED 909999, a 2020 model with 50000 km at AED 555000, a 2024 model with very low mileage at AED 770000 and AED 780000, a 2023 model at AED 1699000, a 2021 model with 58000 km at AED 580000, and a 2021 model with 65469 km at AED 685000. Considering the average condition and the fact that the car is a 2022 model with 28400 km, I adjusted the price slightly lower than the listed AED 650000 to account for depreciation and market conditions.
