The bottom line
The Yukon here is an engine-and-electronics gamble, not a body-shop outlier. Repaint rates match the wider fleet and structural repairs are rare, so paint alone should not scare you off. The pattern that matters is under the hood: fuel trim out of range on 52% of these cars, oil leaks and cooling issues right behind it, and active codes common enough that a cleared history is not comfort. Scan before you talk price, then check for wet oil, low coolant, and tired tires. A clean scan and a dry engine bay are worth pursuing; fuel-trim faults, leaks, or cooling trouble are grounds to cut hard or walk.
