To estimate the price of the 2015 Kia Optima I4 2.4L LX (Mid), I first considered the selling prices of similar cars. The closest match in terms of variant and year is the 2013 Kia Optima I4 2.4L LX (Mid) with a selling price of AED 25500 in May 2024 and AED 13500 in September 2024. The 2016 Kia Optima EX (Top) sold for AED 20500 in July 2023, and AED 27500 in July and August 2024, but these are higher trims. The 2017 EX (Base) sold for AED 38000 in July 2023. The 2015 model is between the 2013 and 2016 models, so its price should be higher than the 2013 model but lower than the 2016 model. Considering the accepted offer of AED 25000 for a 2015 EX (Base) in October 2023, the LX (Mid) should be slightly lower. Based on these data points, I estimate the price to be around AED 20000.
