To estimate the price of the 2018 BMW X3 XDrive 30i, I first considered the selling prices of similar cars. A 2018 BMW X3 30i M sport with 71,000 km sold for AED 155,000 in October 2023. Another 2019 BMW X3 with 99,600 km sold for AED 122,500 in July 2024. The 2018 model is slightly older, and the mileage is 77,100 km, which is closer to the first car. The condition is good, similar to the first car. Considering depreciation and the fact that the car is a year older, the price should be slightly lower than AED 155,000. Next, I looked at listed prices. A 2018 BMW X3 with 91,310 km was listed for AED 135,000, and a 2019 model with 94,000 km was listed for AED 125,000. These listings suggest a market price around AED 130,000 to AED 140,000. Taking into account the selling prices and the listed prices, I estimate the market price to be around AED 140,000.
