To estimate the price of the 2017 BMW X4 2.0L I 4 turbo 28i M kit, I considered various data points. The new 2025 BMW X4 xDrive 30i starts at AED 305000. Assuming a 10% annual depreciation, a 2017 model would depreciate approximately 70%, giving a rough estimate of AED 91500. The listed prices of similar 2017 BMW X4 models vary significantly, with a European spec 4-cylinder SUV listed at AED 78000 and a 6-cylinder coupe at AED 95000. The closest match in terms of specs and mileage is the European spec 4-cylinder SUV listed at AED 78000. Considering the average condition and mileage of the target car, I adjusted the estimate slightly higher than the lowest listed price but lower than the higher-end listings.
