2006 Used Automatic Gasoline mileage: 300 KM or more Peace, mercy, and blessings of God be upon you. I am offering you a custom Sierra 2002, renewed and modified to 2006. The difference between the two models is negligible. The car's mileage is 406, and it is subject to increase. The car has been well cared for, its color is rare, and it was renewed by specialists in the Eastern Province, Haider and Abu Hazza, who are visited from the Gulf countries. The car is very clean and a rare piece. Offers vary, and I will not disappoint the serious buyer.
