The car to be estimated is a 2021 Mercedes S580 V8 4.0L 4Matic Standard with American specs and average condition. The only data point available is a 2022 Mercedes S580 4MATIC Standard with Japanese specs, listed for AED 675,000 and with lower mileage of 26,000 miles. Considering the car to be estimated is a year older and has higher mileage, we should expect a lower price. Typically, a car depreciates around 15% per year. Applying this depreciation to the listed price, we estimate the 2021 model to be approximately 15% less than the 2022 model's listed price, which would be around AED 573,750. However, considering the higher mileage and American specs, which might be less desirable than Japanese specs in the local market, we adjust the price further down.
