To estimate the price of the 2014 Mercedes GL500 4.7L V8 Top with 194500 km mileage in average condition, I considered several data points. First, I looked at the selling prices of similar cars. A 2014 GL500 Top with 125500 km sold for AED 71000 on 2024-02-10. Given the higher mileage of the target car, I adjusted the price downwards. A 2016 GL500 Top with 135000 km sold for AED 72500 on 2024-05-09, and another 2016 GL500 with 152000 km sold for AED 80000 on 2023-11-07. These prices suggest a depreciation trend with higher mileage. The accepted offer for a 2014 GL500 Standard with 167800 km was AED 75000 on 2023-11-25, indicating a higher value for the Top variant. Listed prices for similar cars ranged from AED 59500 to AED 79000, with the closest match being AED 72000 for a car with the same mileage. Considering these factors, I estimated the market price accordingly.
