GMC Sierra 2500HD 2007 Used Automatic Gasoline mileage: 335 KM or more 4WD Peace, mercy, and blessings of God be upon you. GMC Sierra HD 2007 4x4. Mileage: 208,000 miles. Cruise control, manual windows. 6-liter, 8-cylinder engine. 8-bolt. Floor 4x4 shifter. 6-speed transmission. Airbags deployed. Transmission and engine changed to 2013 model, according to the previous owner. I have worked on the suspension: control arms, bushings, shocks, ball joints, water pump, spark plugs, wires, and throttle body cleaning, costing me around 6 to 7 thousand. There are still some minor issues, but I just traveled with the car last month from the south to Mecca to Riyadh, and thank God, it performed excellently.
