Kia Optima نص فل 2017 Used Automatic Gasoline mileage: 1 KM Kia Optima for sale. It had an accident in the front and the car has been repaired with original parts and has no issues. I changed the engine to a Mitsubishi 2400 cc and the engine mileage is currently 14,000 km. The engine is brand new imported. There are minor notes like the oxygen sensor and the evaporation system only. Other than that, everything else is fine.
