To estimate the price of the 2016 Kia Optima 2.0L I4 EX (Top) with 191000 km mileage, I primarily considered the offers accepted by sellers as they provide a realistic market value. The offers for similar cars ranged from AED 28500 to AED 30000. Specifically, the closest match was a car with the same variant and similar mileage (191000 km) with an accepted offer of AED 28500 on 2024-04-18. Other relevant offers include AED 29000 for a car with 193000 km and AED 30000 for a car with 178000 km. The listed prices of similar cars ranged from AED 29500 to AED 33000, but these are generally higher than the actual selling prices. Considering the condition of the car is average, I leaned towards the lower end of the accepted offers range.
