To estimate the price of the 2015 Mercedes S400 V6 3.0L Turbo Standard with 122500 km mileage and average condition, I considered several data points. First, a similar car with 94000 km in good condition sold for AED 112000 on 2023-11-08. Given the higher mileage and average condition of the target car, I adjusted this price downwards. Second, an offer of AED 115500 was accepted for a similar car with 81000 km on 2024-04-30, which is higher than the selling price due to lower mileage and better condition. Third, listed prices for similar cars ranged from AED 89000 to AED 130000, with the most relevant being AED 110000 for a car with the same mileage and AED 111000 for a car with slightly lower mileage. Considering these factors, I estimated the market price by averaging the most relevant data points and adjusting for condition and mileage.
