GMC Terrain SLE 2008 Automatic Gasoline mileage: 300 KM or more GMC Terrain 2008 Peace, mercy, and blessings of God be upon you. The car is good for going and coming, and there are no issues with it, and the air conditioner is cold. As for the body, I don't know what's wrong with it. I bought it like this. The car's mileage is 365,000 km. New registration, recently expired inspection. Whatever offer is made, it will be his. May God compensate me and compensate you.
