To estimate the price of the 2015 BMW X5 3.0L TC I6 turbo 35i with 208410 km mileage in average condition, I first looked at the selling prices of similar cars. A similar car with 205000 km sold for AED 49500 on 2023-12-11, and another with 160200 km in good condition sold for AED 67000 on 2023-08-14. Given the higher mileage and average condition of the target car, it would likely be valued lower than the good condition car. Next, I considered offers accepted by sellers: a similar car with 206530 km had an offer accepted for AED 51000 on 2024-07-11. This is a strong indicator of the current market value. Lastly, I reviewed listed prices: a car with 208410 km was listed for AED 64000 but not delisted, and another with 206530 km was listed for AED 47000 and delisted on 2024-07-20. Considering all these data points, the most relevant and recent selling price and accepted offer suggest a market price around AED 51000.
