To estimate the price of the 2014 Mercedes G63 AMG with 138000 km mileage, I first looked at the selling prices of similar cars. Two cars with 73900 km mileage sold for AED 174000 each in March 2024. Given the higher mileage of the target car, its value would be lower. A dealer sold a similar car with 160000 km for AED 148750 in August 2024, which is a closer match in terms of mileage. Listed prices of similar cars range from AED 139000 to AED 215000, but these are generally higher than actual selling prices. Considering the average condition and higher mileage, the estimated market price should be closer to the dealer's selling price but slightly adjusted for the lower mileage compared to the dealer's car.
