To estimate the price of the 2012 BMW X5 xDrive 35i with 253000 km mileage in average condition, I considered several data points. First, I looked at the selling prices of similar cars. A 2014 BMW X5 xDrive 35i with 100321 km in good condition sold for 81500 SAR in November 2023. A 2011 BMW X5 xDrive 35i with 255872 km in good condition sold for 25000 SAR in December 2023. A 2014 BMW X5 xDrive 50i with 184000 km in average condition sold for 66500 SAR in August 2024. Given the target car's higher mileage and average condition, its value should be lower than these examples. Next, I reviewed listed prices of similar cars. A 2012 BMW X5 xDrive 35i with 253000 km was listed for 53000 SAR, and another with 265257 km was listed for 42000 SAR. Considering these listings and the actual selling prices, I adjusted for the car's condition and mileage to arrive at a fair market estimate.
