To estimate the price of the 2016 Kia Optima 2.0L I4 EX (Base) with 195700 km mileage, I primarily considered the offers accepted by sellers as they provide a realistic market value. The closest match is the same car variant with the same mileage, which had an offer accepted for AED 28500 on 2024-06-28. Other similar offers for the EX (Top) variant ranged from AED 28500 to AED 30000, but these are for a higher trim. The listed prices for the same variant and similar mileage were AED 28000, which aligns closely with the accepted offers. Considering the car's average condition and the most recent accepted offer, I estimate the market price accordingly.
