Kia Optima 2014 mileage: 300 KM or more Peace, mercy, and blessings of God be upon you. For sale Kia Optima 2014, mid-option. The car has driven more than 300,000 km. The engine was replaced around 2016. Reason for replacement: I changed the oil at a shop and the engine seized. I took it to warranty, but it wasn't covered. I installed an engine, and it's been working fine and is excellent up to today, installed in 2016. The transmission is excellent, and the chassis has not been opened. The frame is sound. The airbags deployed due to an accident about 7 years ago. I've been using the car since it was new and it has no issues. I repainted it due to fading and replaced the suspension parts.
