This sounds bad, but I would take it to the shop that performed the inspection, have them check it out. Was the car overheating when you were driving it?
No, there were no signs of overheating as far as sound, smell,warning lights or leaks. I have been told by several mechanics if the engine cannot be manually cranked then it's gone.
sounds like it
