To estimate the price of the 2015 Mercedes A250 I4 2.0L Turbocharged Standard with 115000 km mileage, I first considered the actual selling price of a similar car: AED 40000 for a 2015 model with 138000 km sold on 2024-08-13. This car has higher mileage, so the target car should be valued slightly higher. Next, I looked at listed prices of similar cars. The closest match is a 2015 model with 115000 km listed for AED 48000, but listed prices are generally higher than selling prices. Another similar car with 118600 km was listed for AED 56000 but delisted on 2023-11-04, indicating it might not have sold at that price. Considering these data points, the actual selling price of AED 40000, and adjusting for the lower mileage of the target car, I estimate the market price to be slightly higher than AED 40000 but lower than the listed prices.
