To estimate the price of the 2013 Kia Optima I4 2.4L LX (Mid) with 268369 km mileage, I first considered the selling price of a similar car with the same variant and specs but lower mileage (160636 km) which sold for AED 25500 on 2024-05-02. Given the higher mileage of the target car, I adjusted the price downwards. I also looked at a similar car listed for AED 14000 with the same mileage and variant, which provides a lower bound. Considering the average condition and the higher mileage, I estimated the price to be slightly above the lower bound but significantly below the selling price of the lower mileage car.
