To estimate the price of the 2012 Kia Optima I4 2.4L LX (Mid) with 246000 km mileage, I analyzed the listed prices of similar cars. The closest match is a 2012 Kia Optima I4 2.4L LX (Mid) with 298000 km listed for SAR 28000. Considering the mileage difference, I adjusted the price slightly lower. Other 2012 models with different variants and higher mileage are listed between SAR 22000 and SAR 23500. 2013 and 2014 models with similar or higher mileage are listed between SAR 27500 and SAR 33000. Given the car's average condition and the fact that listed prices are generally higher than selling prices, I estimated the market price accordingly.
