Chevrolet Impala LTZ 2016 Used Automatic Gasoline mileage: 1 KM The car is excellent and has no issues, but last week the engine was hit by something, possibly a rock or something I don't know what it was.. Mileage is over 450,000.. By God, if it weren't for circumstances, I would have kept it with me because it is one of the best cars I have owned.. The car is fully loaded with camel-colored seats. There is a dent in the rear of the car, shown in the pictures, and the car is very clean for the user.
