To estimate the price of the 2014 Kia Optima I4 2.4L LX (Mid) with 296000 km mileage, I considered the following data points: 1) A 2015 Kia Optima I4 2.4L LX (Mid) with 165000 km sold for 29000 SAR on 2024-06-24. Given the higher mileage of the target car, I adjusted the price downwards. 2) A 2015 Kia Optima I4 2.4L LX (Mid) with 148000 km sold for 34000 SAR on 2024-04-03. Again, I adjusted the price downwards due to the higher mileage. 3) A 2016 Kia Optima I4 2.0L with 290000 km sold for 26500 SAR on 2024-02-23. This car has a similar mileage but is a newer model, so I adjusted the price slightly downwards. 4) The listed price of a similar 2014 Kia Optima I4 2.4L LX (Mid) with 296000 km is 30000 SAR, but listed prices are generally higher than selling prices. Considering these data points and the condition of the car, I estimated the market price accordingly.
