To estimate the price of the 2020 Mercedes GLB250 I4 2.0L Turbocharged Standard with 55500 km mileage, I considered the listed prices of similar cars. The closest match is a 2020 Mercedes GLB250 4Matic with 46400 km listed for AED 185000. Another 2020 GLB250 with 87800 km is listed for AED 163000. A 2021 GLB250 AMG with 41300 km is listed for AED 205000, and a 2020 GLB250 with 19305 km is listed for AED 119999. Given the mileage and condition of the target car, I adjusted the price slightly lower than the 46400 km car but higher than the 87800 km car, considering the average depreciation and market trends.
