What about a worst case scenario of low compression caused by worn piston rings? Would this account for inability to start and run? Or would worn rings never even allow it to start (assuming PO was telling the truth about starting and then turning around the car on the driveway)?
Possible but quite rare in an engine with less than 400-500kmi on it. It started cold at least once and that suggests compression on SOME cylinders. Later OM61x engines rarely wear out before half a million miles, but the DO break. Now if it had a couple of cracked rings from playing with starter fluid....
