To estimate the price of the 2019 BMW X7 XDrive50i 40i, I first considered the selling price of a similar car: a 2019 BMW X7 XDrive40i with 49,000 km sold for AED 185,300 on 5 Nov 2024. This is a reliable data point as it reflects an actual transaction. The car to be estimated has slightly lower mileage at 41,886 km, which could slightly increase its value. Next, I looked at the listed prices of similar cars. A 2019 BMW X7 XDrive40i with 49,000 km is listed for AED 218,000, but listed prices are generally higher than selling prices. Other listings for the 40i variant range from AED 195,000 to AED 280,000, with varying mileages. The 50i variant, which is the same as the car to be estimated, has listings from AED 206,000 to AED 339,000, but these have different mileages and conditions. Considering the actual selling price and the listed prices, I adjusted for the lower mileage and the fact that the car is in average condition, leading to a reasonable market price estimate.
