The car in question is a 2013 BMW X3 XDrive 35i 3.0L I6 with 153500 km mileage. We have three listed prices for similar cars: a 2011 BMW X3 3.0L I6 with 142000 km listed for AED 31500, a 2012 BMW X3 2.0L I4 with 128500 km listed for AED 22000, and a 2013 BMW X3 Xdrive 35i 3.0L TC I6 with 109000 km listed for AED 42000. The 2013 model is the closest match in terms of year and variant, but it has lower mileage. Considering the higher mileage of the car in question, we should adjust the price downwards from AED 42000. The 2011 model with similar engine size but older year and slightly less mileage is listed for AED 31500, which suggests a lower bound. Given these factors, a reasonable estimate for the car in question, considering its higher mileage and average condition, would be slightly below the 2013 model's listing price.
