To estimate the price of the 2015 Mercedes GLK250 Turbocharged I4 2.0L Standard with 187300 km mileage, I first considered the selling price of a similar car with a 2.5L engine and 68000 km mileage, which sold for AED 68000 in September 2023. Given the higher mileage and smaller engine of the target car, its value would be lower. Next, I looked at an offer accepted for a 2015 GLK250 2.0L with 150700 km mileage at AED 38000 in April 2024. This car is closer in engine size and mileage, providing a more relevant comparison. Additionally, I reviewed listed prices: a similar car with 198000 km was listed for AED 36500, and another with 150700 km was listed for AED 37000. These listings suggest a market range around AED 36500 to AED 38000. Considering the target car's average condition and higher mileage, I estimate its market price to be slightly below these figures.
