GMC Sierra 2011 Used mileage: 600 KM or more Peace, mercy, and blessings of God be upon you. I am offering a 2011 GMC Sierra. Mileage: 600,000 km, and it may increase. I bought the car without inspecting it, so I don't know anything about it. The paint was redone due to fading and the body was burned on the frame. The car is solid and, God willing, I use it regularly and it's in excellent condition. Modifications: It has an upgraded exhaust system with a cat-back. It has been dyno-tuned, and the 4-cylinder system has been deactivated. The registration is new, and the car is for sale by offer. Please do not lowball.
