To estimate the price of the 2014 Mercedes GL500 V8 4.7L Turbo with 145700 km mileage in average condition, I first looked at the selling price of a similar car with 125500 km mileage sold for AED 71000 on 2024-02-10. Given the higher mileage of the target car, I adjusted the price downwards. Next, I considered offers accepted by sellers: AED 75000 for a car with 167800 km (Standard variant), AED 65000 for a car with 100332 km (Top variant), and AED 75500 for a car with 127300 km (Top variant). The accepted offers for Top variants are close to the selling price, reinforcing the AED 71000 benchmark. Lastly, I reviewed listed prices: AED 82000 for a car with 145700 km, AED 79000 for a car with 148800 km, AED 76000 for a car with 127300 km, AED 75000 for a car with 125500 km, and AED 74000 for a car with 175000 km. These listings are generally higher than actual selling prices. Considering all data points, I adjusted the estimate to reflect the higher mileage and average condition of the target car.
