The car to be estimated is a 2013 BMW X5 xDrive 50i with a 4.4L V8 engine. The most relevant data points are the selling prices of similar cars. A 2014 BMW X5 4.4L V8 xDrive 50i sold for 63000 AED on 2024-01-16, and another 2014 model with the same engine sold for 47000 AED on 2024-09-12. The 2011 model with the same engine sold for 19000 AED on 2024-07-15, but it had much higher mileage. Considering the 2013 model's age and mileage, it should be valued slightly lower than the 2014 models. The 2013 BMW X5 3.0L variants sold for around 36000 to 43000 AED, but the 4.4L V8 engine typically commands a higher price. Therefore, the estimated price for the 2013 BMW X5 xDrive 50i is adjusted to reflect its higher engine capacity and the depreciation from the 2014 models.
