Mazda Mazda 6 2017 Automatic Gasoline mileage: 300 KM or more Mazda 6 2017, mileage 440k. I am the first owner, I've had it since the dealership. Gear has a slight jerk, but it's just a programming issue specific to this model. Engine is guaranteed. Suspension parts have been replaced with dealership parts. The front had a minor impact, which was repaired, and all airbags are intact.
