What was the state of the engine, COLD/HOT, for the testing? Pressure tests are meaningless COLD, plus, plug removal would require extra torque.
Determining the cause of the leakdown simply involves squirting a bit of motor oil into the spark plug opening, crank but no start the engine briefly. If there is now less/noral leakdown the piston rings are at fault.
How much is the owner asking?
Stuck plug is a bit of an enigma. Most shops would have gone ahead and removed the plug. UNLESS the effort required was judged to be REALLY extraordinary.....
Oh, broken plug might well have been the "wrenches" fault. Was is broken beforehand...? No real way to know.

Good points. And BTW; that broken plug in cyl #1 could have easily been caused by using a tool/socket that didn't clear the surrounding fins - it's a bit tighter than the other five plugs. Of course, the tech that broke it has to be slightly ham-fisted... Was the seller removing/installing the plugs himself, maybe to oil something during winter storage?
