Mazda Mazda 3 2018 Used Automatic Gasoline mileage: 90 KM Mazda 3 2018 The car has had its engine replaced. The gearbox needs repair. The engine was replaced 3 years ago, and the new engine has driven 90,000 km. The car is economical. The reason for changing the engine was that the oil pan broke from a stone, causing an oil leak, so I changed the engine.
