GMC Sierra 1976 Used Manual Gasoline mileage: 300 KM or more GMC pickup model 1976, color fiery red. The vehicle has a 6-liter engine and a 3-speed original transmission. Fully renovated body, interior, and everything in it. There are some minor flaws, like the clutch needs adjustment. Also, the valve cover needs to be changed. I don't have a set price, open to offers.
