To estimate the price of the 2018 Mercedes GLS500 4.7TCV8 Standard with 137153 km mileage, I first looked at the selling price of a similar 2017 model with 72500 km mileage, which sold for AED 153255 on 2024-03-24. Given the higher mileage of the target car, I adjusted the price downwards. Next, I reviewed the listed prices of similar 2018 models: AED 158000 (137153 km), AED 150000 (167000 km), AED 145000 (173500 km), AED 152500 (100800 km), AED 191000 (97000 km), and AED 179750 (96000 km). The closest match in terms of mileage and year is the car listed for AED 158000. Considering the actual selling price and the listed prices, I estimated the market price by averaging the relevant data points and adjusting for mileage and market trends.
