Chevrolet Optra 2010 Automatic Gasoline mileage: 300 KM or more The car has an Aveo engine changed and the gearbox is sound. The fans are connected by a wire and I turn them on from the battery. The passenger window does not go down. The car is functional for daily use, I travel with it on highways but it has not been used on steep roads and is not suitable for them. Its fuel consumption is very economical. The air conditioner is broken, I don't know the problem. The registration is renewed, not inspected. It was offered for 7
