Ever not been able to save a car?

I have had a few that make me cringe to this day. My '72 AMC AMX. It had terminal cancer. This was back in the 80's when you couldn't find squat for AMC's. I also sold a '69 Coronet 500 roller to a buddy along with a damn good running '72 440 and matching 727 to put in it. He lost interest and sold it. He didn't even tell me, the bastard, or I would have bought it back. About a year later I found the body in a junkyard with all the precious pieces stripped of of it. :angryfir: I told him that I would never sell him another Mopar... ever!
