Kia Rio استاندر 2014 Automatic Gasoline mileage: 300 KM or more Peace, mercy, and blessings of God be upon you. For sale: Kia Rio, model 2014. I adhere to changing the engine oil, transmission oil, and filters, and consumable parts are changed periodically. The air conditioning and transmission are excellent, but the car's temperature rises, and I believe the problem is with the engine head. Other than that, the car has no issues. It is best for a serious buyer to inspect it before purchasing.
