To estimate the price of the 2015 Infiniti QX50 V6 3.7L Standard with 203500 km mileage, I first considered the selling prices of similar cars. A 2015 model with 132500 km sold for 30000 AED in September 2023, and another with 80230 km sold for 26000 AED in May 2024. The car with 31600 km sold for 45000 AED in January 2024. The 2016 model with 109100 km sold for 53000 AED in November 2023. Given the higher mileage of the car in question, its value should be lower than these examples. I also looked at current listings: a similar car with 201250 km is listed for 22000 AED, and another with 232500 km is listed for 28500 AED. Considering these data points, the estimated market price for the car is likely around 25000 AED, accounting for its higher mileage and average condition.
