In fairness, he is using the same photo as Copart which says "OIL LEAK, DO NOT START" scribbled in yellow on the window... albeit a low res photo and choosing not to show the OSF 3/4 shot which makes this clearer.
I presume that the vendor has attempted, but failed to fix the fault.
I would have thought that the car was driving at the time of the accident, unless a gearbox fault caused the accident. Maybe the disengagement fault is a simple fix, such as a broken wire or an oil supply problem.
Even if it is cheap to fix, the car is too expensive for me to get involved, given its condition and history.
