I had a neighbor who spent several years restoring a 68 Impala SS to show condition and it was stolen less than a year after he finished it. Another neighbor was on his way home one morning after the night shift and found it in a ditch with the door open, not a scratch on it.
The PD asked if he was willing to drive it home for him to avoid impounding it. I was outside talking to him that morning when the car came up the street. The look on his face was priceless.
He got very lucky. I guess the thieves had second thoughts and decided to abandon it.
