I started by looking at the selling prices of similar cars. The most relevant data point is the 2019 MG RX5 1.5L Comfort (Base+) with a selling price of AED 30000 on 2024-07-22 and another similar car sold for AED 28000 on 2024-08-04. These cars have lower mileage (107514 km) compared to the car in question (157100 km), which suggests a lower value for the car in question. The listed price for a similar car was AED 31500, but it was delisted, indicating it might not have sold at that price. Considering the higher mileage and average condition, I estimate the car's value to be slightly lower than the lowest selling price of AED 28000, taking into account the additional depreciation due to higher mileage.
