Hyundai Elantra GL 2014 Automatic Gasoline mileage: 300 KM or more For sale: Elantra car, model 2014. The car has a problem with the transmission. I took it to a workshop, and they said it needs overhauling. We decided to sell it. In general, the car is good. The engine is sound; it was overhauled previously and is in excellent condition. The car has been fully repainted because it had faded paint and some old, scattered dents. Mileage: 400,000 km and above.
