The bottom line
These Grand Cherokees are a lottery: a big chunk land in poor shape while others score well, so the one in front of you needs a hard look, not a vibe check. Start with structure — repairs here run well above the typical used car, and that is walk-away territory. If the frame and accident history are clean, go straight to cooling and oil, because low coolant and cooling faults show up on more than half of them, with engine oil leaks right behind and transmission leaks in the mix. Scan for the active codes that are almost as common, then negotiate on whatever is wet or overheating, or leave.
