I started by looking at the selling prices of similar cars. The 2015 Mercedes ML400 AMG-Kit with 136500 km sold for AED 70000 in August 2023. Given that the car in question has higher mileage (150000 km) and is in average condition, I adjusted the price downwards. Next, I considered the offer accepted by a seller for a similar car with 142900 km at AED 52000 in May 2024. This suggests a lower market value. Additionally, a dealer sold a similar car with 161000 km for AED 58650 in August 2024, which is a more recent and relevant data point. For listed prices, I noted that cars with similar mileage and specs were listed between AED 42000 and AED 78000, but these are generally higher than actual selling prices. Considering all these data points, I estimated the market price by averaging the most relevant and recent selling prices and offers, while accounting for the car's condition and mileage.
