"original motor" what does that mean? Rebuilt? Have the heads been redone? It is well known the AFM motors have issues with the lifters and oil consumption. I bet its at least had the typical AFM repairs done.
Thats what I would have thought but according to the customer it has had no engine or transmission internal repairs. I should have phrased that different. I checked the warranty history and my friends shop does all his repairs and said they have only done maintenance and suspension work. He is a very regular customer of his shop and is proud of what it his Yukon has accomplished and we don't think he is lying. I'm surprised it has not had oil consumption or cam issues. That's the reason I titled this "Impressive". Not so much because of the mileage.
