To estimate the price of the 2018 BMW X3 Turbocharged i4 2.0L 30i, I first considered the selling prices of similar cars. The 2018 BMW X3 30i M sport with 71,000 km sold for AED 155,000 on 2023-10-20, and the 2019 BMW X3 2.0L Twin Turbo I4 with 99,600 km sold for AED 122,500 on 2024-07-07. These cars have lower mileage and are in good condition, suggesting a higher value. The 2018 BMW X3 M40i with 138,635 km sold for AED 85,000 on 2024-11-01, but it is a different variant with a larger engine. For listed prices, a 2018 BMW X3 Turbocharged I4 2.0L with 186,995 km is listed for AED 61,000, and another with 114,000 km is listed for AED 104,000. Considering the target car's mileage of 158,500 km and good condition, I estimate its market price to be slightly higher than the lowest listed price but lower than the higher mileage car's selling price.
